While the Wii is missing out on a version of Call of Duty 4, the DS is getting a version, developed by n-Space, the lads that brought Geist on the Gamecube. The game will follow the same basic story as its bigger brother versions, as you fight through the story as a member of the SAS or US Marines. No online play has been mentioned yet, but the game will have single and multi card multiplayer. Find out more in Source: IGN
