Snowhiter-IsMy-DaDa wrote It does seem like a DLC 5 would come out, but I don't think there would.

Let's just see what happens on the moon - see if the story ends there. ;)

If there is a DLC, Zombies would not be included on any circumstances.

Treyarch has confirmed that this is the "Season Finale" of zombies.

Chances of that are slim to none. They said this map pack was the season finally.

Activision never releases a map pack that encroached on another title's active or near release time. MW3 juggernaut will take center stage for COD on October. There won't be anymore map packs for BOP.
Nazi zombies will have its season finale in Moon, but another innovative zombie story will probably take shape on BOP 2 or whatever is Treyarch's next COD title.

There won't be a Map Pack 5, but there will be more Zombies in the future (CoD 9). This is from Jimmy Zielinski himself:

"If your question is to ask me if our zombies are from Der Riese, this would be a good opportunity to re-explore the WAW maps to search for further clues as to the truth behind the origins of the zombies. As to Moon specifically, of course there will be clues to the past and other story elements, but dont be surprised to discover a few hints as to what may be coming in the future."
