Has Mob of The Dead saved Black Ops 2 zombies?

As we all know, Mob of The Dead is quite possibly the best zombie map since Der Riese on WaW. And also, we know that Tranzit was an epic fail and Die Rise is ok. But I don't think it was just me, but I thought that Treyarch had given up on zombies! I just want to know what you guys think of Mob of the Dead and if Treyarch can ever do better than this! Thank you for your time!
