It's appearing very likely that the new Call of Duty will be announced next week. The info comes courtesy game reviewer Jim Sterling who broke the news via Twitter...
The next Call of Duty will apparently get unveiled by next Tuesday. Getting listed in retailers at any rate. pic.twitter.com/eYnVX5spdh

As for the who, what, when, where and why we don't have any information on that. It could be a re-release for all we know...although that's not likely. We'll find out soon I'm sure.
