Take this with a grain of salt, because even if anything comes of it, it's still going to be a ways off.

But according to Gamercenteronline.net Street Fighter IV's producer Yoshinori Ono said that doing another Capcom vs. SNK game might happen.

He mentioned that Street Fighter 4 happened fairly casually, because the fans demanded it, it helped the game get made.

He seems to feel that another Capcom vs. SNK title could go down the same way.

But don't get your hopes up for another Marvel vs. Capcom title any time soon, according to Capcom V.P. Christian Svensson, Activision holds the Marvel license until roughly 2013.
