The time acceleration technology in the Alicization arc is the foundation for Brain Burst in Accel World
Yui and Star Sapphire are the same person.
For that matter, Kirito and Leyfon Alsief are related.
Akihiko Kayabaya is/was affiliated with the Templars/Abstergo.
"PoH", the leader of the "Laughing Coffins", will return in a future arc.
The last scene of the anime episode 11 is a metaphor for something else.
Kirito and Asuna's pseudo reality warping abilitiesThere are a few moments in Aincrad where it's described that Kirito or Asuna so things that shouldn't be possible in the system of Sword Art Online. There is some speculation of Maybe Magic, Maybe Mundane, but in reality it is simply a function of the Nerve Gear, albeit an unsuspected one. In times of great worry or duress, it's been shown the human body can do things far beyond normal physiological limits. Since the Nerve Gear works by intercepting signals meant for the body and transfers them to the avatar, it only makes sense that these "override" mental signals would transfer as well. Future plots and stories:
ALO and GGO will connect with each other.
There will be prequel stories/novels covering the adventures of Suguha/Lyfa in ALO and Shino/Sinon in GGO before Kirito joined each respectful game.They would flesh-out more on the other characters like Lady Sakuya, Recon, Sigurd, Dyne, and Spiegel.
We will learn what the other Unique Skills from SAO are.We already know 2 of 10 them, Holy Sword and Dual Blades; the other 8 were not elaborated on. When ALO implemented Sword Skills it is said that 10 were removed and there were 10 Unique Skills.
The SAO game contains an early version of the Incarnate SystemAt the end of volume 1 (episode 14 in the anime), this is how Asuna and Kirito were able to cancel a paralysis condition and delay their avatar's death, respectively.
An American-based company will cause trouble late into the story.
Akihiko Kayaba is still alive, in hiding and watching/helping Kirito and his friends from afar.
SOA takes place in a world where the Virtual Adepts won.
Sachi is alive. In a manner of speaking.
Full-Dive technology is The Ancient Precursor of neural interfacing/capsuleer technology in EVE Online.It somehow makes sense that way, seeing what Kayaba had been able to do (high-powered scan to convert himself into digital data) - the reverse of that, although extremely difficult, seems plausible - it is the foundation for clone-jumping technology in EVE that keeps capsuleers immortal. In the same sense, the capability of controlling one's avatar in-game by using the brain can easily be transmuted to 'controlling a spaceship with nothing but your mind through a neural interface/link'. It is also stated that the ancient civilizations that existed in wormholes e.g. Sleepers were masters of virtual reality.
The fact that Kirito is an orphan is actually a plot point and the identity of his parents will be explored later on.
We haven't seen the last of PoHSo far two high-ranking members of the Laughing Coffin have made a comeback. I see no reason why their leader, the game's most feared Hero Killer, should not make one as well.
It is revealed that since entering SAO, Kirito has been his own version of The Truman Show.The Beta Testers for SAO weren't actually there to beta test the game. Unknown to the players, it was actually an audition process, for one "lucky" player to become the star of their own series. Kayaba, likely, was the actual producer of the show, selecting Kirito personally. By the time the game proper started, the actual game was able to happen at the same time, on another server. Kirito, and 10000 actors were all placed into the series we saw. This in turn would explain all the aspects of the "game" that didn't quite make sense. Kirito's unexplainable ability to be far more powerful than anyone else? The plot said so. The huge number of girls who all clamor for our hero? Potential love interests to see which one had the most chemistry before being written as Kirito's girlfriend. Asuna got the highest ratings, so she was chosen... And unfortunately, her character development dissipated when she suddenly needed to be the main love. None of the players actually died, they were just written out of the show for dramatic effect. The final clash with Kayaba? Season finale. (Which, of course, when it didn't go as planned, required a little Ass Pull to keep the plot going.) And the whole plot of ALF? New season... Which of course wasn't as good due to Seasonal Rot.
Sword Art Online (or one of the other games) will allow married couples to create AI children.Because The Dev Team Thinks of Everything.
Kirito will become a police officer specializing in investigating internet crimes.The fact that they make VR helmets that can kill people if they die in a game means that the police force will need to investigate a whole new brand of crimes that they don't know how to investigate. Enter Kirito, who has been doing this for years to same his own life and the people he loves.
The guardians in ALO were Alfs.Just because no player could ever turn into one, doesn't mean they weren't in the game.
All the guys that played as women in SAO where stuck in the female underwearIt's said that when you switch cloths underwear shows for a brief moment. It's said that you don't actually put on or take off cloths like normal. The underwear is meant to be there for modesty. It's said you cant take it off. It's said in the books that peoples cloths didn't change and the anime explicitly showed this to be true. So logically a large number of men, specifically ones who started the game as G.I.R.L.s would still be have that as the default.
Kirito and Asuna survived the final battle of SAO because Akihiko Kayaba spared them.He wrote it into the game that instead of killing the players ten seconds after their HP hit 0, anyone who was defeated during the final battle would not be killed until Kayaba won the battle, and tie goes to the players.
Ginta Toramizu was an SAO player.Come on, he's obsessed with fantasy- could he really ignore the premiere of full-immersion gaming?
Red-nosed Reindeer was Kirito's confession to the families of the fallen Black Cats of the Full Moon.That's why it's in Volume 2 and not Volume 1. Though it's set during the Aincrad Arc, it's actually Kirito telling the story after he got out to the families of his fallen comrades. He wants to confess his fatal omission and let them forgive him or take their revenge as they see fit.
Someone will pull a House of M on Kirito.Some villain will kidnap Yui somehow, and from her memories extract enough information to create convincing replicas of the Black Cats of the Full Moon. When Kirito tries to rescue her, he ends up getting sucked into their illusion, which was the plan the whole time. In order to escape, he'll have to reject the illusions of a world where the Black Cats of the Full Moon never died.
The survivors of SAO meet up once a year to remember all they've been through together and the ones that didn't make it out.Those who are old enough toast sake To Absent Friends.
SAO will get a video game for the PS 4 that will allow you to play through the entire 75 or 100 floors.Also, the Black Cats of the Full Moon side plot will allow for multiple endings, not only for the Romance Subplot but for the entirety of the game. Kirito will have the choice to join or not to join the Black Cats of the Full Moon, and if he joins them, the incident leading to their deaths will be avoidable. Not joining the Black Cats of the Full Moon or saving them will completely alter the course of the game.
There was no violation of the program with anything Kirito or Asuna did.Asuna breaking the dexterity limit? Kirito just miscalculated. Asuna freeing herself from paralysis? Kirito programmed that in while he was saving Yui. Kirito launching a final attack with his HP at 0? Players were always able to do that; the only difference is that Kirito knew about the 10 second grace period because of the events of Red Nosed Reindeer.
Akihiko Kayaba is Kirito's Evil Uncle.Based on the fact that it's Kazuto and Suguha's mothers who are siblings, it seems pretty reasonable to assume that he wasn't born with the surname Kirigaya. He took on that name when his aunt and uncle took him in and raised him as their son. So are there any clues about Kirito's birth name? Well, after he hacked into a government website at the age of ten and discovered that he was adopted, he confronted his aunt about who his real parents were. After that happened, he started withdrawing himself into MMORPGs and almost completely avoiding Suguha. Akihiko Kayaba was an idol of his until he found out that Akihiko was a nutcase. Akihiko, in turn, seems unduly interested in Kirito. So what's Kirito's birth name? Kazuto Kayaba, son of Akihiko's older brother. Akihiko was the quiet genius of the family, whom Kirito wanted to be just like until he found out that quiet genius was hiding criminal insanity.
Suguha and Shinichi will get together eventually.He certainly wants them to be more than just friends, and she seems like she'd be interested if she ever manages to get over Kirito.
Kayaba never intended for SAO to be cleared or for anyone to die.He was actually hoping that everybody would give up on clearing the game, at least after they found out he was the final boss, and that everyone would be content to spend the rest of their natural lives in Aincrad. Why else would he write the game so that he either dies in the end or kills everybody unless they choose to stay in Aincrad? Why else destroy Aincrad when he is defeated? The death game was just his way of choosing virtual reality over real life and preventing anyone else from choosing to go back to the real world.
Kirito saved himself against Heathcliff, thanks to Klein.
Sugou actually wanted Kirito to log into ALO.
Keita had a crush on Sachi.It is implied that the other Black Cats were Keita's only friends, which would explain why he killed himself after learning that the others died because of Kirito's silence. But what really crushed him was the death of the Girl Next Door that he had secretly loved for years, and she never knew.
Kirito is an Unreliable Narrator.He remembers his feelings from the past as what he currently wants to remember them as. His memories of declining to escort Fuurinkazan on day 1 were colored by his experiences with the Black Cats of the Full Moon. He says that Silica reminds him of Suguha based on how he chose to remember her, not how she actually looks or acts. He downplays his relationship with Sachi after falling in love with Asuna because those memories are both painful and an unwanted interference to his current relationship.
Kirito and Asuna are dead, and everything after their conversation with Kayaba Akihiko is a shared hallucinationBecause it's not a WMG page if someone hasn't suggested that the series is All Just a Dream.
Kayaba had accomplices inside the government.Or at least he was able to bribe some officials to look the other way during safety testing.
Pina is really an AI like Yui instead of an NPC pet.If I remember it correctly Silica mentions in the Caliber story that evil-god type monsters are impossible to tame and control. Taking this line further we can guess that the harder something is to tame, the harder it is to control. Kirito mentions (also in Caliber) that there is always a chance that a pet will ignore a command from its master. Pina as a dragon is rare enough that taming her earned Silica a well known affectionate nickname amongst the mid-level SAO community, it is also mentioned that no one else managed to tame a feathery dragon before or after Silica did it. Putting those together we can assume that Pina should be an extremely moody and hard to control pet, yet Kirito comments that he has never seen Pina ignore a command. Add to this that Pina does not behave like a NPC pet should. In Mothers Rosario someone (I think it was Liz) mentions that Pinas habit of cuddling with Silicas friends (and Yui) is completely atypical for ingame pets. Putting all those oddities together it is safe to conclude that Pina is not a typical NPC pet controlled by simple routines. Instead she is an advanced AI, albeit one with common housepet level intelligence compared to Yuis mostly human mind. Either that or pina is controlled by Silicas actual cat. (Would also explain why she spends most of the time sleeping)
Suguha was flat-chested before the SAO incident.There has to be some reason that Kirito would tell Silica that she looks like Suguha, since by the time SAO is over, she doesn't in the slightest.
Kirito talks in his sleep.Which is how Sachi found out he was a high-level beta tester.
