Today at CES Sony announced PlayStation Now, their new game streaming service that will allow users to play PlayStation library of games through the cloud. The service will be first available in the US on the PS4 and PS3 this summer, followed by PSVita:

Leveraging Gaikai’s advanced cloud-based technology, PlayStation Now will allow you to:

• Play video games instantly across multiple devices, similar to the way you might stream TV, movies, and music.
• Stream full games to all of your compatible PlayStation devices including PS4, PS3, and PlayStation Vita as well as non-PlayStation devices, beginning with 2014 BRAVIA TV models and expanding to numerous other Internet-connected devices.
• Always play the most updated version of your game. With games hosted in the cloud, you can take your game with you – just log in with your Sony Entertainment Network account on a compatible device and your games and saved progress will be easily available.

PlayStation Now will start beta testing at the end of January.
