^They have lied about things in the past though, so it wouldn't surprise me if it turned out to be real. If so here's who I would like
Moon Knight - Basically Marvel's Batman and the game is still lacking a staff user(Marvel having already vetoed Gambit twice). Was supposed to have a relaunch, but got canceled. He could have been one of the characters Marvel wanted to promote.
Scarlet Witch - Could be a female Avengers rep. And Marvel apparently has big plans for her this year. So should could have been one of the characters they wanted to promote.
Medusa - There's an Inhumans movie supposedly in the works. She could also be a character Marvel wanted to promote. Could also have an interesting and unique moveset using her hair powers.
Songbird - My most wanted female Marvel rep. Her sonic screams and maybe a couple wrestling moves could interesting. It'd be also nice to have a Thunderbolts rep.
Mega Man - I'm a MM fan myself, but I mostly want him to would shut up his fanboys. Plus it'll be interesting if he did get in and was hard to use or required high execution and seeing if even half of the people complaining about him would even use him.(IE Strider and PW)
Gene - After playing Godhand, I can see why people want him. He can have almost as many moves as Dante.
Asura - I liked his game and I could see him getting added for Capcom to promote it.
Talbain - Nistuma did say if he could add any more DS characters it would be Talbain.
