If anything, Modern Warfare 2 should be named Call of Duty 5, but Infinity Ward decided not to name it that, it's Modern Warfare 2 instead. Therefore, Call of Duty 5 isn't applicable to Modern Warfare to either.
SO, there is no such thing as Call of Duty 5.
John: For the last frickin' time, Gary, there's no such thing as Call of Duty 5!!! It's World at War, or WAW.
Gary: COD5 IS World at War, and who says WAW anyway? Sounds retarded.
John: It's short for WAW, better than saying 5, because THAT's even more retarded. Now just for that, no I will not play WAW with you. Go away.
Brandon: Hey Marcus, I'm buying COD5 soon.
Marcus: OMG, what is wrong with people?! There's no such thing as Call of Duty 5! WAW isn't 5!!!!!
Brandon: Who said anything about WAW? I'm talking about Call of Duty 5: Modern Warfare 2!!!
Marcus: What?! Oh lord, just get away from me!!!
Call of Duty 5 is rumored to be Call of Duty 5: Modern Warfare 2. This information however was given from mtv . I highly doubt that Activision would give this information to mtv and not release this information to show like G4 but i could see why they would with the masses watching mtv they would get lots of hype for the game. For now we hardcore gamers must sit on our hands and wait and see what the next cod game will be.
-Why not! It's so fun.
-Mabey ill play it when it exists.
Call of duy 5 World at war
Going back to the WWII theme it is set in he south pacific portion of world war two a battle fought on a small island named Iwo Jima
