While GT 5 Prologue is available for download/on Blu-ray, sporting improved AI, and for the first time includes multiplayer up to 16 cars with integrated online features, gamers are surely looking forward to the full Gran Turismo 5 release. Unfortunately those people may be in for a long wait as Polyphony Digital's Yamauchi revealed that the team is currently focusing on adding content to GT 5 Prologue (such as vehicle damage) and there is no development being done on GT 5 until 2009, possibly 2010.
