(RUMOR) - Will GTA be visting Sin City?Online retailer Amazon.co.uk is now listing the highly anticipated next instalment of the massive Grand Theft Auto series on its website. Of course, as weve seen in the past, such listings cannot always be trusted. But if true, then speculation about the games title has been spot on - welcome to Grand Theft Auto IV: Sin City. San Andreas was a name that was being knocked around for some time for the next GTA title simply because its a remaining location appearing in the original top-down GTA series that has yet to be covered by the latest games. However, it appears that an entirely new moniker has scored the vote. Amazon.co.uk has zero info on Sin City at the moment, other than that it is suggesting an expected release date of 5 November 2004 on PS2 (nope, no mention of PC or Xbox versions). However, Microsoft insiders have revealed to us that the company is currently locked in negotiations with Rockstar in order to get an Xbox version out before the end of 2004, although its believed an existing deal with Sony precludes the possibility of a simultaneous release. Watch this space. We contacted publisher Rockstar Games earlier today to confirm details, but all we received was no comment.
