Apparently, a small group of PS3 owners were taken to a location in California where they got to test out a new Sony product, a sort of PS3 remote that very much mimics the functionality of the Wiimote. While there, participants apparently enjoyed minigames such as tennis, fencing and paintball. The demonstrator also showed the folks some Quake on his laptop with the device.
But, before you grab your torch and pitchfork, know that Sony hasn't finalized the product yet. There's apparently many kinks that need to be worked out, as the device is right now dependent upon a large tripod.
