New Call of Duty Black Ops DLC Maps ?

Ok so I herd leaked information that there will be a new dlc called Rezurrection witch will have the upgraded WAW maps with a new map called moon they also said there will be a 5th one so pretty munch my question is this true also did I read it right they said about the 5th one but wouldn't that have area 51 where it ends or will map pack four only have WAW maps or will the 5th be like all the others with moon also sorry if I made this confusing to u

This makes no sense
