I thought so too, but Sony/Gaikai dropped Nvidia Grid support. Sony is gonna try to make their own servers. And here's the scary part: The cloud gaming company, Agawi, is using Grid. Microsoft bought that company a few months ago. Microsoft is technically using Grid now. Probably for Windows 8/ Windows Phone.
Last time I checked, Gaikai was using NVIDIA Grid.
I like cloud gaming. Its quick to setup, buy, spectate..
but I don't like lag, muddy visuals, and a relative ghost town of game support....
