I'll take a guess at MS' plans for Xbox. By 2022 I forsee Surface becoming the new Xbox. The two will be fully converged, by that time, Kinect, PC, and Games will all be served through a single device. They will figure out a method in which the surface can easily sync up with any TV it is beside, be it through a cable or a docking station or wireless. Controllers will still be around, touchscreen will not replace traditional methods of input yet.
I doubt it. MS has to worry about windows' antitrust issues so merging windows and xb1 too tightly might restrict what they can do on the console gaming side.
