Black Ops DLC is inevitable.
No that is not my whole article, so far we know two things for sure about Black Ops DLC, one is that it is the same as it was with MW2, coming to xbox first for around a month then to be released to PS3 and PC. Two is that Activision has bought in a separate company (Sledgehammer Games or Raven software?) to do the Black Ops DLC, which could add a new dimension to the maps and maybe overall gameplay.
I honestly do not think that we do not have long to wait for new map packs to be released, as no matter how much we complained about the price of the map packs for MW2 we still brought them buy the thousand.
Also there are the 4 zombie maps from W@W which came along with the hardened and prestige editions of the game that will probably be released.
This next part is going to be a bit loose on the facts as I got it from a google translated page where “A shooter has apparently a fan in the files”, none the less from what I can tell a User/hacker/Someone from callofdutyseries.de has found loading screens and screenshots from somewhere, two with the names "mp_berlin" and "mp_munich”.
