The just-announced PlayStation 4 might not be natively compatible with games made for its predecessors, but that doesn't mean you're out of luck if you were hoping to play your favorites on the new console. David Perry, founder of the Gaikai streaming service, announced today at the Sony PlayStation event in New York City that the aim is to make the PS4 make use of the PlayStation Cloud to stream older games. This is, of course, wonderful news for fans of PS3-era MMOs (DC Universe Online? Free Realms?) who want to enjoy their beloved titles on the shiniest new gaming device.
