Update: Capcom PR manager has squashed the rumor via twitter. Keep on guessing.
A french site called PS3Gen apparently got a hold of some valuable information. None of this is confirmed but they have put out the entire Marvel Vs. Capcom 3 line up. I don’t know if I would classify this as a spoiler if true, but check out the bunch below. But take it as a rumor for now.
Spiderman, Hulk, Wolverine, Mr Fantastic, Captain America, Iron Man, War Machine Elektra, Thor, X-23, Magneto, Dr. Doom, Shuma-Gorath, Emma Frost, Deadpool, Super Skrull, Taskmaster, Juggernaut, Miss Hulk.
Ryu, Mike Haggar, Frank West, Chuck, Spencer (Bionic Commando), Dante, Chris, Morrigan, Arthur, Amaterasu , Albert Wesker, Zero, Chun-li, Viewtiful Joe, Trish, Tron Bonne, Hsien-Ko, Akuma, Felicia.
I know a few names on the list up there will get some excited. Leave your thoughts.
