If you're in the eco-system, the idea that you can play a game on your phone, pick it up on the TV at home, then at your deck on the Mac at the weekend is pretty sweet. I can't see them making a high end console though, those tend to be money syncs and are going to have smaller audiences as mobile & cloud grow acceptable performance for the mass market. This is why MS are making moves they are. They'll support the home console for a while as they can't lose the legacy Xbox audience, but I think sometime next decade they may make Gamepass/Xbox store a multiformat service and phase out dedicated hardware.
