Grand Theft Auto 4 is a computer game that is expected to be released by Rockstar Games at October 16, 2007. Speculation and rumours about the game are rife. Several statements and actions made by Rockstar staff would appear to support these. Grand Theft Auto 4 will actually be the tenth title in the Grand Theft Auto series, but is anticipated to be built on an entirely new next-gen hardware platform, the Xbox 360. It is possible that the game will be set in an entirely separate plot/locale to its predecessors. PSM and CVG magazines have suggested that the game will be officially unveiled at this year's E3 show and will be a PlayStation 3 exclusive.
But during the 2006 Microsoft E3 press conference, it was announced that Grand Theft Auto 4 would be available for the Xbox 360 and will have exclusive episodic content. After the press conference, Rockstar posted the official Grand Theft Auto 4 website with the Xbox 360 and PlayStation 3 logos suggesting it will be released for both platforms.
