I'm more interested to see what the PSP version will do with the PS3. As others have mentioned, the only real difference between the PS3 version and the PC360 version is that the previously downloadable quests and a brand new quest will come in the box.

This definitely isn't a 'system seller' though, as those fanatics already have the game on one of the other systems. It'd be good for folks who haven't yet played it to pick up though.
