Considering the crazy going-downs at the Infinity Ward offices lately, I'm not seeing the Call of Duty Franchise in the best position going forward. Don't get me wrong, I liked World at War, but not more than I'd liked Modern Warfare (in fact I only picked it up, because I'd like Modern Warfare so much). I suppose though we will see exactly what plans Treyarch has for the line.
Either way, none of that is the point. Bungie officially released the trailer for some of the new features in the Halo:Reach multiplayer, and even though they may steal from Tribes, it definitely worth it, and here it is.
