Nazi Zombies has been continuously getting better. In fact, it's the only reason I keep buying the map packs. I could give a shit over the multiplayer maps.
So my question to you is what exactly you want to see in the next map pack. And if you doubt that there will be one before MW2 is released, just look at when the previous MPs were released.
The original game was released November 11
Map Pack 1 was released March 19
Map Pack 2 was released June 11
Map Pack 3 was released August 6
The development times are getting shorter, so I'd guess that the 4th Map Pack should be released late October to early November.
