I have a very strong feeling that he will be back somehow, because : "Reznov is dead or is he?, there was no body, is he who he claims to be?

Also in 2 of the snap chat teasers, a wolf was shown, and Reznov's nickname is "The wolf".

also if you look at CIA files in Black ops you'll notice that a man is sending some weird emails to some characters like Mason and president, that talks similarly to Reznov, in the email that was sent to the president he said: "Victory Cannot be achieved without sacrifice" and that email was sent a day before JFK's assassination
