Near the release of black ops treyarch announced that they would leave clues/easter eggs about the new zombie map, the first easter egg was that on the loading screen of zombies in the tips area there would sometime read "MANHATTAN DOWN !", this was the first clue but the other day i was looking for easter eggs in kino der toten with some friends and i mangaed to find that if you go to the cinema letters area like in the video an if you look on the floor it reads Manhattan Down, sorry for the bad brightness it didnt capture great but to see it just turn the brightness up on your game.There is also notes and maps in the pack-a-punch room in kino der toten and this may back the easter egg but i havent had a chance to have a good look. Now i think both of these are clues to the new map, maybe the four soliders travel to Manhattan to defend off the zombie horde and maybe the down means it will be in a subway, there are rumours that the soliders meet up with another partner a british sergant and that the american governmemt tried to use the element ot try to make their own experiment's but im sure we'll find out soon.
