I don't really know anything about this or how he did it but apparently this hacker guy person-man found some sort of codes in Black Ops that lists the DLC zombie maps.
Here's what he said:

"This is only for Zombies DLC at teh moment.
Anyways, to those of you wondering how I know this, in MEM2 you can actually find a list saying dlc1=Five,dlc2= so on, so forth, and I took a look at some pictures I could find in the 1/25/11 update and saw 'preview_zombies_pentagon'.
Now this doesn't 100% ensure that we are getting these, but hell, why would the developers add the 'change map' option to zombies, along with adding these pictures in the update?
List of DLCs:
DLC 1: Five
DLC 2: Nacht Der Untoten
DLC 3: Asylum
DLC 4: Deap Ops Arcade
DLC 5?: Unkown?

If this is true, I wonder why they didn't add "Five" from the beginning :/
