Microsoft has already given a release date for Halo 4!  It's Release date is 11/6/12! You can pre-order it now! Halo is being deeply worked on and trying to make everything about this game bigger and better then the previous ones! They are  focusing a lot on Chief in this game Chief has been graphically improved and in the game physically. All the weapons, vehicles, and enemies have been graphically improved also! 343 Industries is trying to give you the best halo experience yet! They are also working a lot on multiplayer and will be a lot more fun! They are creating new multiplayer levels from scratch. It's going to a great game and will probably be sold out as soon as it hits stores!
