As you can clearly see by the watermark on this image, IGN has the exclusive announcement of Street Fighter IV for the iPhone. The game will feature a mix of old and new fighters, as well as multiplayer over bluetooth. I guess to keep that fighting in the arcade feel. Not much information beyond that, we could talk about the controls, but I mean they are right there on the screenshot. Street Fighter IV for the iPhone and iPod Touch and well I guess the iPad will be available in March.
