A post on Call of Duty's community Web site confirms the launch date for the PS3/PC version of the DLC and also listed a description of the maps available:

Mirage - A town in Mongolia's Gobi Desert, in the aftermath of a sandstorm with sand dunes scattered in between buildings with one structure directly in the center; perfect for sniping and creeping up on enemy players.

Downhill - A ski lodge in the French Alps with both an accessible interior and working Ski Lift for transport up the mountain for the perfect cover (or death trap).

Hydro - This large map - in a Pakistani hydro-electric facility - is perfect for long distance killing and with working flood gates to block paths/take our enemies, could be the best map in the DLC.

Skate - A radically new map set in Venice Beach, California. The map transports players to the historic birthplace of skateboarding, where they will have to learn to use ramps and half-pipes for cover.

Die Rise - A new Zombies map set atop buildings that are literally falling apart
