Well i think that it will be Ok.
At first I think that the maps need to be better because the black ops ones were sometimes boring.
Like Moon, this map disappointed me the trailer was awesome but the map wasn't good. It was boring, I think it better a map with a good history like Kino der Toten and Ascension.
Than come the weapons they were really good, but maybe you're right the game needs more weapons,new weapons specially for zombies not the same of multiplayer and a huge map. I think the perks were really, really good.
But your ideas are available too
