Honestly, a PC with Steam, and XBox 360 controller, and an HDMI cable is all I really need. I've moved to doing that pretty exclusively and it works wonderfully. Bonus, I don't have to re-purchase games to play them on my laptop or in my office.
Where is the Steam Box? I would pay Valve $800 if it guarantees 1080p@60 games for several years. Both the XBox One and PS4 likely do not have enough power to do that for most games.
Most people didn't realize that MS was pushing the envelope with their purported "Cloud processing tech", which was supposed to be based on Remote processing of a few threads (A.I., Physics, etc) and even had a new programming paradigm for it (based on prioritized threads that could be processed either locally or remotely)
As someone who has done game development (no longer though), I can tell you absolutely nobody is going to do AI or Physics through Microsoft's cloud infrastructure. Absolutely nobody. Never was, and never will. It doesn't make sense.
