It's not uncommon to find listings for unannounced games on retailers' lists. Because they have to update databases and prepare for the launch of a game, retailers are often privy to release information earlier than even much of the press. Such is the case with the next game in the Grand Theft Auto series, Sin City.

Rumored for months to be either Sin City or San Andreas, it looks like Vegas won out. A search for Sin City on Amazon's UK site will pull up a page for Grand Theft Auto IV: Sin City, scheduled for release on November 4, 2004 in Europe. The console of choice listed is not surprisingly the PlayStation 2, but with last year's release of the Double Pack, an Xbox port is not out of the question.

We know absolutely nothing about the game outside of the title's implication that the game will take place in Las Vegas-like city - perfect, considering the theme and tone of the previous games. We can only assume that Sin City will use a modified GTA 3 graphics engine, and that the game will be a small evolution for the series as opposed to a revolution.

We attempted to contact Rockstar Games to get an official comment, but the company had nothing to say, not even a "no comment."

We'll have more on Sin City as it happens.
