During Microsoft's E3 press event, Microsoft showed off a new Forza title that is built for the Kinect.
Using Kinect, you can now get inside the car and explore interior like you would if you were sitting inside of the real deal. Steering will be done with your hands and it looks quite sexy.
I can now finally do what I've done with the controller in my hand, minus the controller.
Forza Kinect will be available sometime in 2011.
