I think this is just as much a response to the wii u as an all out assault on roku, google tv, apple tv and of course cable companies. They kind of waved their hands at it but they plan on offering the ability to start a video on any device and finish it on the xbox. The number of partnerships announced along with ability to use IE on the xbox and your tablet as a remote for the browser (along with your voice which is still the killer feature of kinect) they have developed a tv box that makes competitors step up their game not just playing catch up to others.
