Well with a next gen system: Look at how GTA was on the PS1 and look at its first outing on the PS2. Thats about how much they're going to improve. I'm guessin about 5 cities, some connected, some not connect but instead out in the middle of the sea. Maybe one jungle island with no people on it, or it be a military base instead. The possibilities are endless and no matter what we guess, it'll blow us away and hit us where we least expect it.
