I would argue that there are a couple of innovations here that haven't been tried (to my knowledge) by the previous attempts. One is the wifi directly connected controller (so it bypasses the display device for lowering input latency), the other is, supposedly, advance algorithms to estimate inputs to reduce lag. The latter, of course, is something that FPS servers have been doing for a while but I don't believe this has been tried before in terms of cloud game streaming.
