A great deal of details about "Modern Warfare 3" were leaked a few weeks ago, but that doesn't stop us from getting excited about the release of the first official trailer for the game. In true "Call of Duty" tradition, there are plenty of explosions, action, and gunshots to be heard and seen in the brief video. It's a little taste of what's ahead, but we doubt that it's enough to keep us amused until the "Call of Duty: Modern Warfare 3" release — which is scheduled for November 8, 2011.
