FALSE RUMOR: MvC3 Roster Leaked?

UPDATE: Producer Niitsuma said that none of the Fantastic Four will be in the game, which proves this list false!

First let me say that this list definitely differs from one some guy showed me at EVO, but not by much; I distinctly remember M. Bison being on his list. Regardless, people on the Internet supposedly found this list in the Flash code on the Japanese website, which has since been changed. Did it really happen? Is there any reason to trust this list? Probably not... but here it is anyway:
