Is Project Iron Wolf the next Call of Duty game?

Let’s do some math shall we? Developer Treyarch makes games for Activision. Since last year, they’ve been working exclusively on Call of Duty games? Therefore, when a mysterious project shows up on the Xbox Live account of a supposed Treyarch employee….

Project Iron Wolf was spotted by the site Se7ensins.com on the account of a friend who apparently works for Treyarch. The rumored employee has not been named, and it really could be anything; but hell it could be a new Call of Duty game already in the works. Thoughts?
