Capcom announced that it will be bundling Marvel Super Heroes and the first Marvel vs. Capcom into a package called Marvel vs. Capcom Origins. The game will use a similar display set-up to Street Fighter III: Third Strike Online Edition and will feature GGPO online play.
These games are notorious for having a number of infinites in them, which could make online play a little dicey. Otherwise, I am eager to take a crack at Marvel Super Heroes again. I thought the gem mechanic in that game was really interesting.
