As promised last week, here is the trailer for the newest iteration of Call of Duty.  Called Call of Duty: World at War, this brings the series back to World War II, and is developed by Treyarch, the developers of Call of Duty 3.  However, the game uses the same engine as Call of Duty 4: Modern Warfare, so World at War looks as stunning as Modern Warfare.  However, for the gameplay, only time will tell. Enjoy!
