Rumor: Sony may get extra GTAIV content after all

Coming from a recent interview with Phil Harrison, 1up was curious why Sony was letting exclusive downloadable content for Grand Theft Auto IV slip through their fingers. It seems that, perhaps, the PS3 will get their own content for the upcoming classic sandbox game. Phil responded thus: " ... we have a great relationship with Rockstar and we're actually working closely with them on a number of initiatives, so I do know some things that are going on, but I'm not able to share those with you now." Insert theories here.

If we can think of anything, we'd imagine that Sony is trying to get the content for the 360 version over to the PS3 version either as standard Blu-ray extras on the game disc (so they aren't technically breaking the "exclusive downloadable content" clause or whatever), or that there is some more original material planned for the PS3 version down the road. What are your thoughts?
