PS2 Quiz #9

You all got 4/5 right. I knew the GTA question would stump you all. The next GTA game is going to be set in a Los Angeles-esque city in the seventies. The correct answer is GTA:San Andreas. Well, since it's Friday, and I'm a nice guy, and it's 12:33 here, I'm going to give all of three of you the win.

Umm... I don't see where you got that title from. I did a lot of searching, and all I could find was the tentative title (GTA IV). A link would be nice.

EDIT: I've seen RUMOURS as of now, but no actual proof.
