There's a big investigation underway over at Microsoft since it was discovered that Halo 2 hit the internet.

The pirate copy of the game, which is thought to have begun circulating last night, claims to be a PAL version with French text, suggesting that it may have been leaked during the localisation process for the hugely anticipated game.

Microsoft is not worried about this hurting their sales so the scheduled release date for November 9th is still on track.
