The official patent has now been spotted confirming what the newfangled controller will look like and revealing that it will utiltise a"hybrid video capture and ultrasonic tracking system".
The patent continues...
"The captured video information is used to identify a horizontal and vertical position for each controller within a capture area. The ultrasonic tracking system analyses sound communications to determine the distances between the game system and each controller and to determine the distances among the controllers."
Just because Sony has filed the patent doesn't mean that the product will ever meet the light of day, but a motion-sensing controller for PS3 seems to be the next logical step.
Doesn't it look like a wonky Wii-mote with a Nunchuck stuck on the end?
