Seems like Sony just applied for a patent of a next generation controler for its PS# that features 3D motion sensing, just like a WiiMote.

Game interface tracks the position of one or more game controllers in 3-dimensional space using hybrid video capture and ultrasonic tracking system

Looks a lot like a WiiMote to me, and if you watch the patent pictures the setup is also pretty similar. Apparently the ps3motes look like double lightsabers that can be split to be used one-hand or 2-hands. I guess everybody want to replace those complicated remotes with natural motion input devices!
