With Treyarch's Call of Duty: World at War blowing up store shelves, and Activision already confirming the inevitable 2009 first-person follow up, this comes as no surprise -- Infinity Ward isn't working on any new content for Call of Duty 4: Modern Warfare.

Responding to users on the Xbox.com forums, Community Manager Robert Bowling breaks it down, citing the main reason as simply not having the resources. 

"Every level designer/texture artist/environmental artist/etc. working on a new map for a previous game is one less working on a map for a future game," he says. 

He mentions that the perfect scenario would be to ship with a ton of maps, and then release a lot of content for free. He says that "in a realistic development environment, it's near impossible," using Criterion (and their Burnout Paradise DLC) as an exception joking that they have "magical DLC fairies."

Their future plans? To have "a polished/stacked game at launch and a dedicated team for DLC post-launch while everyone else looks towards the future."

Hey, that sounds a lot like Criterion's "magical DLC fairy" set-up. Can you imagine an Infinity Ward-developed Call of Duty game with Burnout Paradise-style DLC support? Wake me up -- I must be dreaming.
