We've heard the rumours about Microsoft's Wii-killing, motion-sensing Xbox 360 add-on set to debut at E3, but the Ars Technica crew thinks they got a hands on with it—15 months ago.
Ars thinks that the new tech is actually based on the ZCam 3D camera that we covered way back in December of 2007, a company that was later purchased by, you guessed it, Microsoft.
It seems like pretty good news if true, because Ars was impressed with the tech when they did a hands-on with it back in January of 2008. Microsoft has had a long time to work with it since then, so if it was good 15 months ago it's probably a lot better now. It all makes a lot of sense to us, but we'll have to wait and see how accurate all this conjecture is until E3 next month. [3DV via Ars Technica]
