Wow. Just when the fighting game resurgence didn't look like it could get any crazier, Capcom and Namco dropped the bomb on us, outside on the streets at Comic-Con now less, that they're teaming up to make Street Fighter vs. Capcom for Xbox 360 and Playstation 3.
The engine looks to be the same used for Street Fighter IV and the upcoming Marvel vs. Capcom 3, and Capcom is confirming early Tag Team play with assists and tag combos, so you can bet the tournament players are going to be all over this one.
The roster is, as with any fighting game, hush-hush for now (presumably to trickle it out to keep media buzz high), but Ryu and Chun-Li have been confirmed for Street Fighter's side, with Kazuya Mishima and Nina Williams announced for Team Tekken.
The teaser trailer (sorry, no gameplay footage) is below the jump, and you can find a gallery of released screenshots here.
