You hear sirens at the end of MW3, so one direction they could take with MW4 is that Captain Price has become a war criminal and goes into hiding, seeking out help while evading both the police and the remainders of Makorov's faction. Also, remember All Ghillied Up? It took place in the 90's, and Captain Price was a leutainant in that mission, meaning he was in the service for quite some time that has not been explored yet. Basically, they could either resume the story as it is, or explore the past of all the characters.
