Live action Modern Warfare?! Yes please. For a while there was thinkins' that it might be viral ads by Activision/Infinity ward/whoever it is thats producing the next game (North Korea?), but it turns out its a project by an ARG project team - see quote from PC gamer:
The new information comes courtesy of Spike TV journalist Geoff Keighley, who has done some digging and revealed that the countdown was created by We Can Pretend, a team from Toronto working on a Call of Duty inspired project. Keighley said that “production sources who worked on the self-funded project call it visually spectacular.”Either way, its freaking awesome. When they planted the breach charges and then splattered that guy? Crazy.
