Black Ops 2 DLC: Orientation rumoured to be next map pack

The second Call of Duty: Black Ops 2 DLC pack is rumoured to be called Orientation.
A supposed image for the unannounced DLC suggests the game add-on will feature four new multiplayer maps (Water, Mobile, Southpaw and Plane), a new Zombies level (Dead High), and a fresh weapon.
As pointed out by MP1st, it's unclear if the image in question is legitimate, but it appears similar in style to promotional material used for - and leaked ahead of the official announcement of - the first Black Ops 2 DLC pack, Revolution.
