FPSRussia has the scoop on what to expect. Watch the whole video and pay attention to what he says at the end. If you go to the call of duty website, there is a picture of one of these quad rotors embedded, but you can make it out.
Also, there are many people blogging about his t-shirt, and that companies name, Tacitus. They feel that name is going to be the developed story line. Tacitus website went up the day FPSRussia released this video.
