Robert Bowling of Infinity Ward has tweeted the above image of the first upcoming DLC for Call of Duty: Modern Warfare 3. It is a screenshot of a map simply called "Park", which will join four additional maps entitled Overwatch, Cement, Italy, and Morningwood (where the men are constantly dissatisfied?).
Bowling also revealed earlier that "the full season of content for Modern Warfare 3 kicks off for Elite subscribers January 24th on Xbox Live"; that is, PS3 and PC owners will have to wait. The DLC will cover Spec Ops and "a variety of things that players have never seen before".
