Evidence has surfaced that Microsoft plans to re-release Turn 10's Forza 3, seemingly as an "Ultimate Collection" with what we can assume would include much, if not all of the game's downloadable content. Australia's OFLC ratings board has listed the potential encore package -- which, if released this holiday, would appear to be a friendly challenge to Sony's long-awaited Gran Turismo 5.

Additional retail sources could not immediately corroborate the Forza 3 Motorsport: Ultimate Collection listing, but we'll update as this story develops.
