In a new video covering Kinect 2.0, Microsoft’s Phil Harrison has stated that the new Kinect, (Kinect 2.0), will be powerful enough to understand two different voices at once, and  that it will also be able to read your lips whilst playing in the dark.
It will also be a million times better than the current iteration when it comes to recognising the gamers face. Kinect 2.0 will layer 1400 points to create a 3d image of the players face, which in turn will be used to good effect on the players in-game avatar.
Pretty close to witchcraft if you ask me!
