If Zombies are a far deeper option than in the past and customizable like Halo's firefight and not just a survival mode like in MW3 than yes I'm buying it for Zombies.
But I gotta be honest. I don;t know enough about Zombies right now so I'm saying no. I'm buying this for the same reason half of the current pre-orders are. Everybody else is playing it. I might as well get in on the fun.
I've only ever truly liked one zombie map- the first one. Since then they'd loaded them with a bunch of junk I don't care about (perks, traps etc.)
I am tentatively looking forward to whats new in this one. I hear there's a proper zombie campaign and new zombie MP modes (hopefully playable in Combat Training.) --- Artiste of the Slightly Funny Deal
