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.

Gran Turismo 5 has been postponed about a month from the originally projected March 2010 release date in Japan. News of the delay came from Sony Computer Entertainment Japan.

This is par for the course in the gaming world I’m afraid this isn’t the first game of the year to get postponed, nor will it be the last.

UPDATE: A Sony spokesperson commented that Gran Turismo 5 has been estimated for a 2010 release in North America and did not see the delay in Japan as impacting the US release
