I hope Hawkeye n' Ironfist make it in.

Kotaku has a live show right now with a Marvel dude, and someone called in asking if the characters will retain some of the comedy that some had in MvC2, and the marvel dude said "oh deffinately, theres some great idle animations, and one of the characters that we havent announced yet will bring the comedy in a big way"... DEADPOOL MUCH? :D
 
he also just said that the stages / backgrounds will be themed this time (marvel AND capcom themed), no more random stages
 
Lastly, he also said Spider-Man is NOT off limits. He also said Activision has the spiderman AND x-men licenses, and we know wolverine is already in the game.

Huh.  A fighting game that I might buy.  I recently bought 2 from the PSN so a number 3 already just might be worth picking up for me. :)

Roided out Redfield

I found an old post of mine on another forum relating to this. The first real sniff of MvC3 came at ComicCon '08 

Could Marvel Vs Capcom 3 be on the way?, well, Marvel certainly seem confident about it. Kevin Feige, President of Production at Marvel Studios gave fans a ray of hope at this years Comic Con, before an official announcement. When asked if a new Marvel vs.Capcom 3 game is possible someday Feige said : " Yes. And maybe sooner than you think."
