I was watching GDC Sonys Press Conference and they unvailed alot of games and even showed some gameplay of Socom 4 with the Playstation Move, now from the video it seemed the gameplay was quite fluent for a motion controller, but likely they asked if motion control might interfear with alot of games and they said no and that Socom 4 will obiviously be support the normal dualshock controller.
