Call of Duty Black Ops Zombie maps?

I've heard that if I buy the Hardened Edition, I will get the 4 zombie maps from WaW and the 3 (?) new maps from Black Ops... can you correct me?



But if I buy the standard edition, how many, if any, zombie maps are given to me? (Without downloading anything)Call of Duty Black Ops Zombie maps?
The standard edition will give you 2 new maps (one which you must complete the campaign to unlock, or at the main menu press Right and Left trigger for Xbox and the equivalent for other consoles to get out of the chair and go to the computer and type in "3ARC UNLOCK" this will unlock the map "Five" and the 3rd map given to you) which is called "Dead Ops Arcade, which is an Arcade style of zombies.
