Most people long since acceded that Halo 3 would sell well, and it has. The big question for the platform, though, was whether it could move consoles; whether it could take back some of the ground gained by the Nintendo Wii since it launched last year, as well as ensure they'd stay ahead of Sony's lackluster PlayStation 3.

Early indications are that the answer to that might be "yes".

Spong is reporting that Chart-Track, a market statistics aggregator, says that during Halo 3's launch week Xbox 360 sales doubled compared to the previous week. Even more unexpected, Halo 3 topped the Japanese software charts, which perhaps goes to show that there's nothing out there for the Wii that people don't already have, and just plain nothing out for the PS3 yet.
