Xbox One "secret sauce" revealed. 40x more powerful than 360 when connected to the cloud.

Does that mean you will need a gold account for single player games?

What happens to off loaded physics, AI calculations when you have a bandwidth cap and normal latency.
60fps games can't spend more then 16 ms per frame on that stuff, that's too short for a average round way trip to a server, and then still render the frame locally.

Cloud mmo type features, sure. I don't see any real time off loading happening. Full game streaming is more likely, but will never be acceptable for sim racers or fighting games for example. Blame physics.
