When you have a franchise that makes nearly a billion dollars per entry, you certainly don't stop the money train. Modern Warfare 4 is currently in production, according to Siliconera, and it will continue the previous entries' story. This sequel will focus on "a battle hardened veteran in his mid-thirties with a nihilistic point of view." Way to connect with your audience, Activision!
Siliconera managed to squeeze some script lines out of its anonymous source, but it's all military jargon that doesn't shed much light on narrative. However, there is supposed to be a scene that takes place in Somalia with John "Soap" MacTavish, ostensibly a flashback.
Early rumors. Early disinterest. Disappointing E3 demo. Exciting summer previews. Hype building. Preorders. Etc. Just wake me when I can play it. Actually, wake me when I can play the one after because I'm done with the Modern Warfare series. For me, Black Ops has overtaken it and is the world I'd like to see expanded.
