Sony full 3D Peripheral Rumor

I hard this from someone long ago when the wii came out that Sony is developing a wii like controller but instead of a sensor bar, it will be fully 3D meaning no more sensor bar.

That's just rumor but here are some news from Joystiq.com stating that GameTech is up to something for the PS2 dubbed RealPlay as in RealPlay Tennis, RealPlay Golf and all the other wii like sports. Sony just doesn't stop copying the competition. But anyways I guess its always nice to have options. *coughcopycat
