Well, call of duty 5 is in the making already, and they are saying that it is gonna be based in world war 2, personaly i am tired of all the world war 2 games , i think it would be a mistake for them to return to the world war 2 era, COD4 is the top selling COD series i honestly think they need to make COD5 some type of modern fighting game maybe even futureistic, does anyone agree with me?
