With all the 'shopping done on these screens, I wonder if there'll be a photo mode a-la Forza, GT5 etc. I certainly hope so.
Actually, I hope they really open up the sandbox with this one, even to the point of a separate mode where you can just create a character and do whatever you like, with no story missions. Maybe with dynamic/random missions to keep you occupied and an economy of some sort, so you can just go nuts and see how long you can survive / how much money you can make. If executed well, it could make the game endlessly entertaining after you've finished the main campaign.
