All development on every mobile version of Call of Duty is being moved from Ideaworks Game Studio to Activision Leeds, UKIE chairman Andy Payne revealed to VideoGamer in a fascinating interview. Specifically, he said "all handheld versions, iOS versions of Call of Duty" moving forward will be handled by the publisher's Leeds studio, which is reportedly headed up by a couple of ex-Rockstar guys, Mark Washbrook and Mark Lloyd.
Payne isn't the sort of guy you'd expect to hear this kind of information from, so it might be wise to take this with a grain of salt. But even as a hypothetical, this is an interesting move. The Call of Duty series have been incredibly popular on the App Store, even in their somewhat limited Zombies-mode only releases. If Leeds is going to focus solely on Call of Duty handheld and mobile, and have the access to the Call of Duty asset pipeline, you could easily see its releases being big steps up from 2009's Call of Duty: World at War: Zombies and last year's Call of Duty: Black Ops: Zombies.
Or, at least, that's what we're hoping for.
