The dlc for zombies will possibly bring the characters back to where they had been (black ops and WAW maps) as it will be needed to stop rictofen in 2025. Better technology may be found at der reise, kino der toten, ascension or even more etc. Items to release richtofen may be at aether (forgot the real name), call of the dead or moon itself. maxis may require you at veruct or shino numa. along with the 2025 download of the map, you get the original map from how it was in black ops (maybe even improved).
