Modern Warfare 3.
Found here on Kotaku, it seems that Modern Warfare 3 will be the concluding part of the Modern Warfare series of the Call of Duty franchise. As the game will continue on Modern Warfare 2's story and will lay to rest the conflict that is going on in the world of Call of Duty. There is also details of what we are to expect from defending New York City from an invading Russian force to stopping terrorist attacks in London to other parts of the world in chaos. So it seems the whole world is getting in on the conflict caused by Makarov.
My thoughts is that this what WWIII is going to be like. Hopefully, it will not be what Einstein stated.
I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.
Knowing the controversial nuclear event in the first Modern Warfare, and the use of tactical nukes in MW2's multiplayer, I do wonder if nuclear weapons will be used again....especially since this is turning out to be a World War III scenario.
Lets just hope Einstein's quote doesn't come to life in this game's universe.
