Microsoft and 343 Studios has just announced that Halo 4 is locked in for a November 6, 2012 release date for the Xbox 360. This is only one part of the new announcements surrounding the game today as the Conan O'Brien show will have a special segment on the Master Chief's latest journey tonight.
This release date pushes back the release of a new Halo from the traditional September window of past games. Probably for the best as it can capture holiday sales far better in November. Check out my first impressions of Halo 4 for more on the game.
