User blog comment:Gman111/Cod 7 Is Not Coming Out This Year, Cod 5 Is!!!/@comment-1899940-20100220011252

We're talking about the main series. People who say, it's not Call of Duty 7, or Call of Duty 5, it's Call of Duty 15!

We're counting MAIN installments, those others are "side" installments. There's only been six MAIN games so far.
