*CONFIRMED*Black Ops Map Pack IV Leaked o_O

After Shangri-La being just released a little while ago, information about the new mappack called Retaliation will release some time in September no exact release date has been confirm as of yet.
"Rezurrection" has been annouced for release August 23rd.

The same website that leaked all other map packs put up a page detailing the next map pack, to be Released in early September(News of possible release August 23rd) called "Retaliation" "Rezurrection"(Yes, with the letter "z" not like it's normally spelt). Activision quickly took the page down. 4 maps and 1 zombie map, again IGN has an article about it.

Mansion: takes place in Castro's secret compound in Cuba.
Cargo: takes place in an frozen shipping center in Greenland.
Metro: takes place in an urban city in Vietnam.
Harbor: takes place in an abandoned shipyard in America.
(These maps might be replaced by zombie maps instead)

5 Zombie Maps

Nacht Der Untoten/Night
Verruct/Asylum
Shi no Numa/Swamp
Der Reise/Factory

The map pack will also include a new Zombies map titled Quarantine, set in Area 51 , the highly controversial military base in Nevada. MOON

This is the information that I've got for you guys, it's a shame the DLC has been leaked this early(I would have posted earlier when the info was exactly released, but, I've been preoccupied and didn't really feel like it) We haven't even fully enjoyed Shangri-la yet and we are being pressured to anticipate the next maps :\
