The problem is, this is a prototype. Cloud power is legitimately going to be there, just not yet. I don't think this will be standard on the xbox one any time soon though. There are simply too many variables. If your connection slows down, part of the frame could be a quarter second of another part, which would be very disorienting. And there's also the matter that not everyone could use the cloud, so devs would still create game under the assumption that you're not using it. Plus this demo is set under ideal conditions, it won't always work that well, if ever. So the way I see it, they won't really be able to fully utilize the cloud they're talking about until they can get almost 0 latency from across the web.
