Earlier this year Microsoft announced a "strategic alliance" between themselves and Rockstar, which would bring exclusive downloadable episodic content to the Xbox360^TM version of GTAIV. However, EuroGamer are now claiming that - according to a source close to Rockstar - the team are working on exclusive supplemental content for both systems, which will be made available for download via Microsoft and Sony's respective online services after the game's release in October 2007.

The source also claims that the downloadable content will take the form of new land areas, which will link into the main GTAIV game world. - "Think of the world as a large island - the new downloadable areas will be like smaller islands linking into it," he said.
