[[WMG: It will cause the 2012 apocalypse ]]
It's hibernation lasts roughly 27 years. The last time it woke up was in 1985 and It completely destroyed Derry. Now that King has revealed It's existence to the world, It will be forced to destroy the entire planet when It awakens in 2012 forcing humanity to start over so It can continue to exist in relative peace. At least until someone decides to write another book about It.
** This is either {{Jossed}} (if it ever needed to be in the first place), or after getting his face pushed in two awakenings in a row, Pennywise is sleeping in.

[[WMG: IT is a {{Youkai}}]]

[[WMG: IT was responsible for the [[VisualNovel/HigurashiNoNakuKoroNi Hinamizawa Syndrome.]]]]

[[WMG: It being a woman wasn't omitted in the movie.]]
The "Kiss me fatboy" scene was just FoeYay.

[[WMG: The true form of the Deadlights is...]]

An innumerable number of "balloons" glowing with an orange light, floating endlessly. Within each balloon is the soul of one of the children that IT killed, causing them to float.
** That would actually make some sense.
*** It would also strongly resemble some depictions of [[HPLovecraft Yog-Sothoth.]]

[[WMG: The Beldam in Film/{{Coraline}} is related to It]]

She just uses a different tactic to get her food.
* There is a lot to suggest this. It's explicitly stated that IT is female. The final form is a [[spoiler: spider]]. It shape shifts for the purpose of MindRape. The other world could be near to the deadlights. Even the setting could be a cryptic clue to the Beldam's true nature. Oregon [[Film/StandByMe has doubled for Maine]] before, this is just Neil Gaiman (a Stephen King fan) doing the same with Derry as he did for Castle Rock. He only gave the setting as Ashland to keep the clue cryptic.
** And the cat could be a reference to the turtle, the intelligent, perhaps omniscient, animal who lives in ITs world and counteracts her will. Man, this is getting clearer and clearer.

[[WMG: The Turtle and IT are tied into the Dark Tower universe.]]

Roland explains that each beam has two guardians on the ends, and one greater demon elemental in the middle. The Turtle is Maturin, and IT is the demon elemental of fear. For that matter, Maturin's death was the result of the ongoing attempts at "breaking" the beam, and Bill and company inadvertently led to further weakening the structure by killing IT.

[[WMG: Stan Uris + Beverly Marsh = Stan Marsh]]

The creators of ''SouthPark'' got the name for one of the show's main characters from ''{{IT}}''. Makes you wonder if a character named Beverly Uris will be introduced on the show.
