Developed at Rockstar North, Grand Theft Auto IV marks the first occasion that the series has been released simultaneously on an Xbox and PlayStation platforms. Previous games in the series (since it went 3D) have always debuted on a PlayStation console, with the Xbox eventually getting a port of the game.

"Few franchises have had the profound impact on our industry as 'Grand Theft Auto,'" said Peter Moore, corporate vice president of the Interactive Entertainment Business in the Entertainment and Devices Division at Microsoft. "Gamers can't wait to play "Grand Theft Auto IV" in high definition on Xbox 360, and we couldn't be more excited to have the title on our platform from day one."

To tie in with this announcement, Microsoft has announced a strategic alliance with Rockstar Games to provide episodic content for Xbox Live.

"Through Xbox Live, we have a unique opportunity to reach out to our audience in new ways," said Sam Houser, executive producer and founder of Rockstar Games. "This strategic alliance allows us to craft experiences that fully leverage the on-demand distribution power and sheer size of Xbox Live."

The official press release for Grand Theft Auto IV is scheduled for simultaneous release on Xbox 360 and PlayStation 3 on October 16, 2007 in North America, with the European releases a few days later on October 19.
