Kinect - Where YOU are the controller!
For those who do not know about it, this is the new buzz phrase involving the Microsoft's answer to the Nintendo Wii. To quote the official Xbox home page, "Kinect brings games and entertainment to life in extraordinary new ways – no controller required. Easy to use and instantly fun, Kinect (formerly known as “Project Natal”) gets everyone off the couch. Want to join a friend in the fun? Simply jump in. And the best part is Kinect works with every Xbox 360". Kinect is to come out in November of 2010.
They already have official promo videos out, so look for yourself (if you wish).
