It means PC players will get their hands on Capcom's Namco crossover more than two months after console players. The game will be released for PlayStation 3 and Xbox 360 on March 9.
Also announced were four new characters: Street Fighter's M Bison and Akuma, and Tekken's Ogre and Jin. While Capcom-Unity claims these are the final four fighters to be revealed, enigmatic producer Yoshinori Ono hinted on Twitter that more are still to come.
Capcom also noted that organisers of Wednesday Night Fights, a weekly California tournament, will be streaming Street Fighter X Tekken for the first time tonight on Twitch TV.
