If you stop and think about it, why should they use a new engine. It's not like they are coding for newer hardware than the 360 and ps3, but hey if they want their games to look like ass then that is their prerogative. They just reuse the same material again and again, coffee stains and all while adding some particle effects and some new map skins. When they are at the deadline they slap a CoD title on it and make millions.
On a separate note his mention that Valve is still releasing games on the source engine while this is true, the games Valve puts out look infinitely better than anything TreyArch has ever shit out.
