OK, I’m a little late to this party. Sony Japan has Turntable software for the PS/2. Been out for about a year now, no US release on the horizon. Rather than thinking of this as convergence, I think it’s more of a cross-interface passage. An experienced gamer has a rich vocubluarly of gestures and reactions that they can simultaneously channel through the game controller. It may make more sense to turn the controller into a musical instrument than a keyboard.
