The pending launch represents the first time PS4 owners will be able to play the previous generation's games on their new console.
No news on Euro launch
The platform is powered by Sony-owned Gaikai and will eventually bring game streaming to the PS3, PS4 and PS Vita, as well as Sony's PS Vita TV set-top box, Bravia televisions and Xperia smartphones.
The company is yet to announce plans for a European launch and is yet to confirm whether games will be available to stream a la carte or in as part of a Netflix-style all-you-can-eat subscription package.
Sony did confirm plans to extent the private beta to more PS3 owners, who've so far racked up 5,000 hours of game time on the platform.
