According to The Verge Microsoft are getting ready to announce the release date of Halo 4 later today and that date is going to be November 6. Obviously the release date is something we were expecting to find out as Halo 4 is making an appearance on Conan tonight, and November has been rumoured for a while. The big surprise here is that Microsoft will go head to head with Assassin's Creed and Call of Duty, instead of opting for the traditional Halo release month of September.
