[Edit: The December date was originally published on Amazon back in August, with an update to the page recently pushing the date back to the 29th. We've contacted Amazon for comment.]
There it is, on Amazon. Gran Turismo 5. December 29th. Granted, this is just one page on the internet for the game, but with Tokyo Game Show flaring up this next week the announcement of a GT5 release date is inevitable. And what a better way to do than it by letting Amazon ruin the surprise for everyone!
Anyhoo, check out the Amazon page, and pray pray pray that the game FINALLY releases.
There might actually be a reason for me to put down Forza 3 for a while.
