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.

In a bid to improve sales of the PSP Go, Sony has announced plans to offer 10 free game downloads. The free downloads are available to all users who registered their PSP after April 1, 2010.

“On PSPGo we’ve decided to innovate with that particular business model,” Sony Computer Entertainment UK sales director Mark Howsen told MCV. “Next month we’re launching a free ten game offer. And this isn’t just older titles–we’ve worked with third parties and there’s some really good core products.”

Sony Computer Entertainment America (SCEA) and game developer Polyphony Digital have just unveiled the final cover art for the highly anticipated PS3 racing game, Gran Turismo 5. You’re looking at the final cover art for the North America region.

The cover features the all-new Mercedes SLS AMG which is one of nearly 1,000 cars meticulousy recreated for the game. The SLS AMG can reach top speeds of 197 mph.

Gran Turismo 5 will be available this March for the PlayStation 3 system.
