The teams are fighting for new battle techniquesFans have noted that several Dead Fantasy characters have used moves from Tekken. Perhaps the plot of Dead Fantasy is that characters from different video games are thrown together in the same world and need to compete to gain powers from the opposing team. Winning team takes all.
What do the G and S stand forIn a poll that Monty Oum did, he said that there will be Dead Fantasy 6, 7, 8, 9, 10, 11, 12, 13, G, S, Prologue & Finale. What do the G and S stand for? I may be wrong, but I think he said there would be spinoffs of Dead Fantasy. G and S might be those spinoffs (but as for what they stand for, your guess is as good as ours)
Hitomi is a Jedi.Isn't it obvious? You've got blind fighting, using magic she's completely unfamiliar with and, of course, the Force Slap in Part V. Shame lightsabers don't yet exist in the DF universe/multiverse/wherever the hell everybody is.
By the time this is finished, we're going to need a flowchart to figure out who's fighting who and why.Sooner or later the DOA crew and the Square Enix Crew are going to start trading fighters. DOA might get themselves a Tifa via brainwashing, and I'm guessing that sooner or later the DOA crew and their constant in-fighting is going to lead to a Big Damned Heroes moment for one of the SE crew. Probably Kasumi and Hayate, with Cloud coming in for the Big Damn Heroes moment.
Hayate is playing the Manipulative Bastard here.Parts III and IV introduced some plot to the story, but most notably V has tied in even the previously thought plotless parts I and II into the overall story arc. However, while the early parts seem very much a "well, we're all badasses here, let's have a nice bout", the implications change due to the Easter Egg in part V, of dialogue (presumably Tifa's) stating "I have to help her", after which she falls off a cliff, teleported to the battle area. The feather seen in both scenes implies it's Rinoa that's responsible, but one wonders why Tifa would be recruited for something like this, and in fact, come prepared with a variety of Materia, if it was a friendly spar. In fact, the FF crew are fighting for their lives in every fight, and Ayane literally destroys the entire tower at the climax of II, so they're far more serious about this than it seems. However, notable members of Team Tecmo aren't in on the plan. Kasumi didn't know her clones would be called in in IV, even though they don't attack her till she attacks them, and Hitomi slaps Hayate across the face after the events of V, clearly angry with what he's done. And finally, the fourth member of team Tecmo is Rachel, a demon hunter from Ninja Gaiden who goes right for Rinoa(a witch) upon her arrival. All of these are people that could be convinced to go along with Hayate's plan, or manipulated... and Hayate's been shown in canon to care more about the welfare of his clan than his family, given he sent kill squads after Kasumi in DOA 3. It's entirely possible he plans to trade the Square Enix fighters to DOATEC to protect his clan from their constant attention, given DOATEC's constant use of Mugen Tenshin ninja as weapons. Given Monty's comments on "are you sure 'that person' is a good guy?" in interviews, and that "something unexpected happens in VIII and IX", it's entirely possible that the sides may change from company lines to heroes and villains. This leaves it ambiguous what Helena's game is, but that's for waiting and seeing.
All combat in DF I and II was in a simulated environment. Rinoa transported the fighters into the real world at the end of DF II.Note the rather sudden shift between DF I&II and DF III, IV, and V. We go from the characters regularly getting shot and sliced without any real consequence in the first two to having Tifa and Kasumi getting horribly maimed as they fight their enemies later on. At the very least, it seems as if the reality they were fighting in during the first two videos was something much different than in the latter three.
There will be a Matrix-syle gunfight between Yuna and the soldiers seen at the end of DF V.We've already seen one giant mook fight between the ninjas and Tifa, and you know Monty wouldn't have made those soldier models if he didn't plan on using them. He's already had practice with Gun Kata.
Additional characters who will appear in future Dead Fantasy installments will include...

Dead Fantasy's version of Rinoa is actually Monty's concept for a Kingdom Hearts Rinoa.She got trapped in Radiant Garden as a small child when the Heartless took over, but some Kingdom Hearts version of Hyne gave her sorceress powers that allowed her to survive. She's so much stronger in Dead Fantasy than she is in Final Fantasy VIII because she's had the majority of her life to master her powers and learn how to fight with her weapons, unlike the original Rinoa who didn't have much combat experience pre-game and only had a disc and a half to get used to being a sorceress. She carries a gunblade in honor of Squall, the same way "Leon" has her emblem stitched onto the back of his jacket in Kingdom Hearts to remember her. She's able to teleport people around because transporting herself the heck away from the Heartless without the help of a gummi-ship would logically be the first thing she'd learn to do with her powers. And, of course, this would be the reason why she showed up with Kairi.
Tifa has one more, very big deal, materia left.Go to Dead Fantasy V, 01:23 and look at Hitomi's legs to see how materia look when clothing is covering them and dimming their glow. Now fastforward to 05:21, and look in the middle of Tifa's back, in an area otherwise in shadow. An area that not only still has her white shirt covering it, but which would have also had her leather overshirt over it if she were in a less advanced stage of Clothing Damage, which would probably have blocked any light from escaping at all and drawing attention to it in its out-of-the-way spot if anyone were ever, say, trying to knock every piece of materia out of her body. I'm sure I don't need to remind everyone which materia glows white. Who's to say that a particular dead Cetra won't show up at some point?
Team Dead or Alive are villains, or at least more evil than team Final Fantasy.Flame bait, I know, but think about it. Team DOA always goes for battles where they outnumber their opponents. They're the ones who  ninjas, and in parts one and two, a new team mate of theirs would show up and unbalance the fight until another Final Fantasy character showed up and made things even. And in a fair fight with no numerical advantages, it seems the Final Fantasy crew get the edge. Also, it seems the DOA faction has an army of ninjas, while FF doesn't have any sort of army of Mooks.
Helena and Hayate attempt to obtain DNA for an army of fighter clones.They have somehow caught wind of their universe intersecting with FF multiverse, so they set out to capture the FF fighters for studies. Having tested the cloning technique on Kasumi, they've first captured Tifa because she seems to be the most powerful fighter after Rinoa. Rinoa herself, though, is out of their reach and is quite possibly their primary opponent in all this. Helena seems to be the mastermind, and Hayate, the reluctant Dragon, but the rest of the DOA cast is not in on their plan, though Hitomi, for instance, trusts Helena (for whatever reason) so much, she lets go of her grudge against Hayate when she arrives.
In response to the army of ninjas, the FF team will unleash an army of Tonberries.After all, how better to balance out a team of incredibly fast, teleporting ninjas than with a race of creatures who can laugh off a sword to the face and shank your kneecaps in retaliation? Fighting professional killers? Everyone's Grudge/Karma! And of course, it would be awesome.
Cloud getting Character Development?In Part V, Cloud can be seen pushing the Buster Blade aside as he races to catch Tifa. Considering this once belonged to Zack, I found that to be pretty surprising. With Zack's memories in him, he'd treat the blade with a lot of respect. But when it seems that Tifa is going to vanish, leaving him behind...to me, it spoke that Cloud may finally be willing to put the past behind him for the sake of those he cares for. I may be over analyzing it, but...(shrugs) Just a thought.
It's all part of Rinoa's planRinoa probably teleported all the girls in the arena. Why the girls? Because she knew the guys would follow them for nay reason(Chronic Hero Syndrome/Always Save the Girl, etc.) She separated team Final Fantasy knowing that they were weaker. She wanted Tifa to lose, because she knew Helena would take her to the headquarters and help, so Tifa could infiltrate easier. Whatever Rinoa wants the D.O.A. characters are trying to protect, so also goes with what Monty Oum said,"it's not about who wins", so there are not really good or bad sides. She's probably trying to stop something from happening. Rinoa also seems to be Author Appeal judging (possibly wrongly) by the fact that she overwhelmed everyone in Episode 2 and the fact that she has the best fanart (if Transient Princess says anything) by Monty.
Kairi's fighting style will make use of itself in the futureSpecifically Naminé's, because it's too awesome to lose.
Kairi/Naminé is actually Xion.Given the fact that Xion can take on different forms by canon, this could be possible. The way Kairi just changed into Naminé like... well, we might just see Xion sometime in the future installments. (Yes, I'm crossing my fingers).
The story will eventually have a Big Bad Duumvirate in the form of Final Fantasy and Dead or Alive villainsAnd, as per the rules of "Let's You and Him Fight" Crossovers, the heroes of the Final Fantasy and Dead or Alive universes will keep beating each other up until the villains move in for the kill, thus forcing the heroes of both worlds to form an Enemy Mine, and fight the Big Bad Duumvirate. It's probably best not to speculate any further until the future episodes drop some more hints, but I would at least put my money on Sephiroth and Alpha-152 showing up, being the most iconic One Winged Angels for their respective series.
