Well, if you really wanted to make it tie in with the upcoming (and movies that have come out)…you add
Marvel side: Thanos, Ant-Man, Black Widow, Nick Fury, Loki
Capcom side: 8 Bit Mega Man (yes, I know you have Zero, but could also work Mega Man in there, and making a HD pixellated Mega Man would be epic), Random DarkStalkers Character, Ken, Asura, and another SF character.
As far as I know Marvel greenlighted the update and the ball is in Capcom’s court now. Funny how things change, a month ago I was convinced the game was finished and now I think an update is rather likely based on fan demand (and $$$ for Marvel and Capcom if its a paid update).
Could you point me to where they said this? I know they’ve responded warmly to the fan demand, but I haven’t heard anything about green-lighting.
EDIT: Though Frank Tieri, the writer for the game, left this little tweet ten days ago. https://twitter.com/FrankTieri/status/290560463228526592
Maybe “greenlight” isn’t the right word but it seems like there has been a lot of acknowledgement for the demand for this, from both Marvel guys on Twitter and the MvC3 Facebook page.
The fact that Sven said “we can’t talk about anything” instead of just saying “nothing is in the works” suggests that something is probably in the works.
