Head of Polyphony Digital (a subsidary of Sony Computer Entertainment and creators of the Gran Turismo series of games), Kaz Yamauci has made a post on Twitter apparently stating that he believes that the upcoming PS3 title Gran Turismo 5 could require a massive 10GB of hard drive space to install the game for smoother game play.

Gran Turismo 5 will be released at the beginning of November this year for the Sony PlayStation 3 and can actually run using just 256MB of hard drive space. CVG thinks that the ‘recommendation’ by Yamauchi to fully install the game is to “take the heat off the Blu-ray disc” which makes sense.
