Treyarch Developing New Call of Duty?

For those who aren't in the loop, the past few years have been back and forth with the Call of Duty series. We know that Infinity Ward is working on Modern Warfare 3 but what about Treyarch?

Several new job listings have been spotted on the Treyarch official site and Gamasutra. All the job listings have the following at the end of the listing:

“With a successful track record, extensive infrastructure, and strong management, Treyarch has the solid foundation it needs to pioneer the Call of Duty franchise in the future.“

My guess, November 11th 2012 will be the release date for this new CoD game. But, only time will tell.
