In his D.I.C.E. speach today Phil Harrison made a comment that could suggest a LocoRoco game for PLAYSTATION 3. It seems likely that this will be a game for the PlayStation Store and most likely being controlled with the sixaxis tilt-sensor.
"11:02: Turning it over to the audience for questions, the first is 'What's Phil playing that isn't on a Sony platform?' He says he plays things for competitive analysis, but that the PS3 has enough for him. He mentions that he's been playing the next LocoRoco game, then he turns to a new PlayStation 3 downloadable game called Super Rub-O-Dub. It's the duck demo from E3 turned into an entire game."
