You may remember Gaikai, a company built on the idea of cloud-based gaming. The idea was that a remote server would run the game and stream all graphics and sound to a player's device, which would allow underpowered or obsolete machines to run modern, graphically demanding games on high settings. In 2012, Sony purchased Gaikai. Now, they've announced at CES that their cloud gaming tech (dubbed 'PlayStation Now') is just about ready for the public. CES attendees will be able to try it out, and Sony will begin a closed beta test in the U.S. later this month. Full release is planned for summer. It will first support streaming to PS3s, PS4s, and certain Sony TV models. Later, it will expand more broadly to various non-Sony "internet-connected devices." Players will have the option to rent games or to subscribe for continued access. Forbes reports, "According to Sony, gamers who own disc- or digital-based games will not have access to those games via PS Now free of charge."
