While Capcom offers Street Fighter 4 and Super Street Fighter 4: Arcade Editionthrough Steam already, players have to register a Games For Windows Live account on top of Steam for multiplayer. Capcom's Neidel "Haunts" Crisan saysUltra Street Fighter 4 will forgo GFWL entirely for Steam.

Crisan tweeted the news earlier today, and so we followed up with Capcom. The company confirmed the news and added that Ultra Street Fighter 4 would be available on Steam and "other digital distribution partners" when it launches next year. Capcom also clarified it hasn't "made any announcements regarding our broader PC lineup."

Ultra Street Fighter 4, due for Xbox 360, PS3 and PC, was announced at this year's EVO fighting game tournament. As the latest re-issue of Street Fighter 4, this entry in Capcom's flagship fighting series adds five new characters in Elena, Rolento, Hugo, Poison and a fifth, unknown character who will make his/her fighting game debut.
