So, can the Kinect really do all of these thigns?

I didnt watch the video, but I can tell you what it does. Yes, its kinda voice activated, you can only say limited commands, and only on the dashboard. It really does register your whole body as part of the controller. Some games do gave interactions that are voice activated, like MJ experience. It is kinda futuristic with the menus since you use your hand to interact. Overall, it does pretty much what they say.
