At the Sony PlayStation 4 press conference, Gaikai's Dave Perry seemed to confirm the rumors that the system would not be backwards compatible with PS3 games, but Sony has big plans to allow users access to the PlayStation back catalog.

While Perry said PS3 games are "not natively supported," that doesn't mean the extensive history of PlayStation games won't be available to users.

He did not mention specifics, but Perry claims the system's cloud service will allow users access to a wide array of past PlayStation titles at a later date. We'll have to wait on details to see which titles make the cut.
