MvC2 on PSN and Live still continues to sell. Still. It is still among the top ten of the best selling PSN games. I think with MvC3 it will be the same thing, but maybe on a smaller scale.
Every day someone discovers Marvel through a cartoon, movie, comic book or other and to me as a Marvel fan, it still seems that Capcom has still done the best by them regarding video games. Konami’s X-Men arcade game and Sega’s Spider-Man arcade game are huge exceptions lol! There’s a few more exceptions but moving on.
SSF4 on the other hand probably won’t continue to sell that much more than it has, or just not as much.
Of course comparing the sales of a DL game with a ten year history to a full on console game may not be the best way to go, but time will tell.
I love MvC2, SSF4 and MvC3 so no bias or anything.
I don’t really trust numbers this early but it seems like MvC3 is selling well at the very least.
