I believe the DLC will be timed exclusive missions packs with some extras(cars, jobs, minigames, etc.) 10 hours of content probably translates to about 15-20 missions or so. The twist will probably be a new character(perhaps a minor character from the main game.) Maybe even an all new character or create-a-character. They'll probably add some new indoor areas, but nothing like the size of a city. That's my take, anyway.
Think: GTA4:Liberty City Stories (1&2)
