The Capcom Vs SNK games are the only one's that I like. The Marval game's are just terrible imo. All those crazy 25 hit super combo's and normal move's which fill the entire screen, awful!

I wouldn't mind seeing a Capcom Vs Sammy game, but I don't think Sammy have enough character's to bring to the party.

As far as new 2D beat 'em up's go i'd like to see either Street Fighter 4, (not gonna happen.) or just a Street Fighter game with nice new high res sprites like in the Guilty Gear game's. I mean look at Morrigan in Capcom Vs SNK2, the sprite looks awful as it's just been pulled out of a 10 year old Darkstalkers game.
