All we've got to say is that they'd better be selling seats to the first living room demonstration of this tech when somebody gets cute and grabs a real baseball bat for a demo. Sony has filed a patent for technology using the PlayStation Eye which can detect regular objects in 3D space and file them away in a database for later use in gameplay. Naturally, the camera already does object motion detection of a sort with the blocky embedded codes on Eye of Judgement cards, but this seems to be taking that tech to a new level, and would imply that you won't necessarily need to be waggling that goofy ball-on-a-stick controller that Sony demoed at E3 for all upcoming motion control titles for the PS3. But for some reason we're sure we should be scared of whatever combination it does turn out to be.
