The LittleBigPlanet stars are tired of platforming in all your user-created levels. They're taking a break by joining the cast of Hot Shots Golf. Update: The content will be available tomorrow, March 12th. According to the PlayStation.Blog, acquiring the various Sackboy costumes will involve buying the premium DLC and downloading a patch.
Update 2: It's not free! Sorry folks! Price should be revealed in Thursday's PSN update.
