Specifically, Bowling announced that the "full season of content for Modern Warfare 3 kicks off for Elite subscribers January 24th on Xbox Live." As usual, expect the DLC to remain exclusive to Xbox for some time before launching on PS3 and PC.
Bowling didn't drop details on what the first batch of content would contain, though he did hint MW3
DLC would cover a wide spectrum, including Spec Ops and "a variety of things that players have never seen before." All of this is made possible by the massive development team, featuring Infinity Ward, Sledgehammer and Raven Software.
Oh, and if you're having trouble finding this particular video on Call of Duty Elite, it might
be because it's in the Elite TV section, which is reserved for premium (read: "paid") members.
Bowling has tweeted
an image from the upcoming DLC, a map known simply as "Park." It's worth mentioning that Park was mentioned in a rumored leak
late last month. Other maps mentioned included Overwatch, Cement, Italy and (ahem) Morningwood.
