I love the GTA series and can't wait for this to come out. I just really hope it has planes in it, that was really lacking from 4. Adding back in the territory stuff would be nice as well, although I hear Saint's Row has that so that might do for now.
Abyss, they made Red Dead which was pretty original, even if it was the same style as GTA. In fact the last cowboy game I played was Outlaw on the Atari!
