I got my grubby little mitts on this.
Yeah, it's awesome. It's as good as the second one. Maybe a little less characters then the last one but that's not necessarily a bad thing per say. ( Sometimes, too much is like not enough. ) One thing that is very different from the second one is the controls. Instead of a four buttons attack scheme, ( Two hard and two medium attacks. ) they opted for a three buttons scheme plus one special which you use to initiate the air combos and do certain special moves. The three buttons are low, medium and hard attacks. But there's no difference between punches and kicks. This was apparently done to facilitate the task for newcomers to the game. ( Although I'm pretty sure that a newcomer who's reading this might think I'm speaking chinese. ^-^ )
The graphics are kick ass. The character models are so sleek it's unbelievable. Some of the Marvel characters look like their movie counterpart. ( I.E. Ironman and Thor. Or maybe they look like their comics version. I don't really know anymore since I don't read comics much lately. ) And like Street Fighter IV, the animation is very fluid. The characters that have appeared in the earlier version pretty much play the same way that they did before. ( I.E. Same animation. ) Although some of their special moves have changed to fit the new button scheme. But the roster isn't only consisted of older characters. There's a plethora of new fighters to choose from as well. From Ghosts & Goblins Arthur, to MODOK from the Marvel Universe.
All in all, this is a very good fighting game. I give it a 4.5 thumbs up out of 5. Here's a video to show you the awesomeness/madness that is Marvel vs. Capcom.
Until then, this is me signing out.
