I'm most interested in how Rockstar is going to get around the DVD's size restrictions. GTAIV just barely fit on one disc, so unless Rockstar is going to make the next GTA PS3/PC exclusive or the series is no longer going to grow, we're most likely looking at a multi-disc 360 version.
However, with the Grand Theft Auto series being the penultimate sandbox games that they are, it's very curious how they can split the game. My best guess is that the next location for the series will be split in half much like how Vice City was comprised of two main islands.
