According to a new product listing on Amazon France, Gran Turismo 5 will be joining the PlayStation 3’s “Platinum Range” less than one year after its release, on October 5, 2011.

“Platinum” games are the PAL-territory equivalent of the “Greatest Hits” collection in North America, featuring special packaging and a significantly reduced price. Amazon France lists the Platinum edition of the game at €24.98, a 37% reduction of its current price of €39.54. Notably, all previous major Gran Turismo releases have attained “Platinum” status, including Gran Turismo PSP and GT5 Prologue.

As with any retailer release date, October 5 is most likely only a placeholder (another title, LittleBigPlanet 2, is also listed to go Platinum on that date). The timing, however, would likely not be a coincidence, with the launch of Forza 4 coming October 11th.
