It will be awhile, and probably never, til there is an XBOX exclusive GTA game. Rockstar signed a contract with Playstation for I forget how long, but I doubt they will even release GTA on more than one system. I think if more people would say "XBOX is the better system" and buy it, that more games would be released on it exclusively. I think game companies would notice the edge XBOX has in sales and go with them instead. I'm sure more games are coming.
lol hkzknight, in your first reply to this topic I think it was, you basically said what Giz said in the topic post.
XBOX2, I have heard that they will be stackable, so you can have XBOX parties and save space, that sortay thing.
