Well, considering all the Easter eggs in Black Ops, we can assume Reznov (or at least his legacy) will appear in Black Ops 2. I would make a safe bet that Reznov appears in the Afghanistan levels, either alive or as a hallicunation. He could end up being Alive in Afghanistan (although this would put him at being 70 years old) leading the Mujhahideen against the Soviets, or he could have really died in 1963 at the Vorkuta camp, and is simply assisting Mason and appears unaged due to him being a figment of Mason's mind.
