Xbox720 leaked?

PC Mag has detailed a leaked document that flashed up on the web for a few minutes which clearly shows that Microsoft has been at the very least thinking about what their next xBox will look like. From crazy glasses that overlay what you are looking at on the screen to a revised version of the Kinect system. Release dates thrown about on the document are around the US 2013 holiday season. I have just started rethinking buying any Microsoft xBox products for now.
