Have you seen or heard about this? It's a new motion controller for the PC not just for gaming but pretty much everything.
No matter how cool it looks in a video I still think motion sensing peripherals have a long way to go. And even though it looks good in a video doesn't mean it'll be good when it hits retail.
I mean do you remember the Kinect preview from E3 2009?
They say it's "more accurate than a mouse, as reliable as a keyboard and more sensitive than a touchscreen.”
I hope it works out though cause it looks pretty cool.
