A really big map like a maze or a city with lots of possibilities and free roaming through different levels of the buildings, that would be epic, like two people are on ground floor and two others are higher than them on a walkway or fire escape both groups fighting zombies from all angles and in this big city, with two groups on each end you have to make your way throught to each other
ALSO as ive seen on the trailer/demo, in zombies you have to pick up a flash light (from the scene underground in the demo) so the lights go out at some point like a power cut and you have to fight with a small flash light

as I think it would be so much fun to destroy loads of them, and also maybe more than 4 players fighting the zombies, which would mean bigger maps! =D
they might not have a grenade launcher but using information given from treyarch to the public, they might use the crossbow to replace the m1 grand and the explosive attachment to the crossbow to replace the grenade launcher
