I'm guessing some stupid phone app that lets you do something similar to what Miiverse does. Somethign phone related is my guess though. Everyone is doing phone shit.
To bad it will look like a total rip-off cause Nintendo is already making a miiverse app.
As for controller, not sure how they can win in this. Any tablet of some sort will be rip-off. A little touch screen on the dual shock will be seen as pointless gimmick and at best compared to dreamcast. Expand on motion and it better blow motion plus out of water or else its nothing new, or kinect.
They would have to really surpise me with something in order for it to look like anything new. Otherwise it will just be a copy of another thing plus more power.
