The service is set to launch later this month in closed beta, and later this summer on PlayStation 3, PlayStation 4 and Vita. As for mobile devices and Bravia support, that's expected by year's end. Given the relative earliness of PlayStation Now, the UI we saw was non-final (and looked like little more than placeholder art). The same goes for the list of supported titles via streaming -- the service will launch with a variety of "marquee PS3 games," though nothing's set in stone thus far. We expect the God of Wars and Gran Turismos of the world will be there on day one, but only time will tell.

Beyond the subscription to access full games, there'll be rental and demo options available through PlayStation Now. But again, none of this is final, and only one facet of PlayStation Now was available for testing here at CES. What we did see was impressive and fulfilled the promises Sony's made when it comes to game streaming, but there's a long way to go before PlayStation Now launches this summer.
