No.

Cause that's crazy talk

PR News asks the question with an obvious answer: Call of Duty Black Ops: Will you buy it without Zombie Mode?

Well, no, we wouldn't. Because it wouldn't be Call of Duty then would it?

We know that the four zombie maps from World at War will definitely be playable in the special editions of the game, but whether that is part of normal play, or zombie co-op is still yet to confirmed.

While there are a lot of questions out there about new Zombie content in Call of Duty Black Ops it is known that the original four co-op Zombie Maps will only be available in the Hardened and Prestige editions. The regular edition will be Zombie-less (of the old Zombie Maps at least).
