Rumor: Full Marvel vs. Capcom 3 Roster Revealed
Apparently, a user of French gaming website PS3Gen(links to Google Translated version of original source) got some source code for Capcom's Japanese site, dug through it, and found the full roster of characters for the developer's upcoming fighting game.
Here's what he found:
Spider-Man, Hulk, Magneto, Wolverine, Shuma-Gorath, Mr Fantastic, Iron Man, Deadpool, War Machine, Thor, X-23, Dr. Doom, She Hulk, Emma Frost, Super Skrull, Captain America, Taskmaster, Elektra, Juggernaut
Ryu, Chun-li, Chuck, Spencer, Dante, Trish, Chris, Morrigan, Arthur, Amaterasu , Albert Wesker, Viewtiful Joe, Mike Haggar, Zero, Tron Bonne, Hsien-Ko, Akuma, Felicia
The list doesn't seem entirely implausible. Although a certain blue bomber is strangely missing, even though Zero and Tron Bonne are there. I would find it odd for Mega Man not to be in this game, but I suppose it's not outside the realm of possibility. Still, given the source and the lack of any official confirmation, take this one with a big grain of salt. I've contacted Capcom for details, but expect a "no comment on rumors or speculation" kind of thing.
