Doesn't mean it's accurate. It was something internal to MS. They would have done the same if it was a roadmap for Excel. That doc was a thing where marketing gets involved and says that things are a good idea because they're hip and tight like a tiger. Take a look at what's happened since it was released internally. XBL has jumped to a streaming entertainment hub. Kinect has taken a backseat from the next new thing in gameplay to a microphone to control NXE (Rise is possibly having gameplay problems as well). The new glass/slate thing is also going to act as a remote control for crap.

The most interesting thing was the price point, but as history has shown, MS/Sony are only willing to take soo much of a loss when selling hardware. As for the hardware, it's good but it's not anything that has developers scrambling to make use of.
