When LittleBigPlanet PSP was first announced, we instinctively guessed there would be connectivity with the PS3 game. Looks like we were right. Players that own the original game will be able to unlock bonus content through a feature Sony is calling "Cross-Talk." No details on what the bonuses will entail, but we wouldn't be surprised if owners of both are treated to some exclusive costumes.
In addition to confirming PS3 connectivity, a leaked retail sellsheet notes that Sony will be planning a "multi-million dollar marketing push" for the game -- makes sense, when you consider the PSP Go is launching this year. Finally, Sony also confirmed plans for a PlayStation Network demo of the game. For the millions of PSP owners that don't have a PS3, this will undoubtedly the very first taste they get of LBP's "Play, Create, Share" motto.
