Nick Calandra, owner of OnlySP (Only Single Player), found some interesting information on the next Call of Duty.
There have been several rumors calling the next title Modern Korean Warfare, Ghosts, Pentagon, and other very unlikely names.
A user on the Call of Duty forums wanted to find some information on the upcoming Call of Duty title and happened to run across a page on the Call of Duty site stating that Dark Skyline is the next Call of Duty.
The page also had a countdown of when the game will supposedly be coming out.
Although the page has been taken down, you can view some screenshots below.
