Speaking in a recent Call Of Duty Elite video update, Infinity Ward's Robert Bowling confirmed that Modern Warfare 3's first DLC pack will deploy on January 24th. Apparently Infinity Ward will be taking a different approach to downloadble content compared to past entries in the franchise, including new Spec Ops missions and "more than just maps."
"The way we’re doing downloadable content this year is unlike we’ve never done before. Not only in how you can get it – in content drops or choose for the collection – but also the type of content you’re getting. We’re doing more than just maps. We’re going to do Spec Ops missions and a variety of things that players have never seen before."
Okay then. We'll keep an eye out for it next year.
