User blog comment:Gman111/Cod 7 Is Not Coming Out This Year, Cod 5 Is!!!/@comment-1729910-20100218183249

@Griever0311 Point taken. This seems to resemble the whole "Valve Game Interconnection Theory". As in, Portal, without a doubt, IS tied together with the Half-Life series. But what about Team Fortress 2?

Infinity Ward has a tight grip on their games, but there's not a lot of evidence suggesting that they are all intertwined. The WW II games do feature "Real Earth" events, and COD is a clone of that, but, I have a question now... ARE the games connected to each other, other than the Modern Warfares?
