Black Ops 2 zombies ideas

So far I would like for two things to happen in Black Ops 2 zombies. I would like to have it to were the gang goes back in time but to prehistoric time with every few rounds zombie dinosaurs. A if the gang goes back and meets themselves and work together to stop the zombie epidemic from ever happening, this way up to 8 people could be in a game.

It has been rumored 8 players will be in zombies as well as sandbox mode. So I hope I can play against 8 players and survive longer if possible. However you have to understand that if it is 8 players, the whole zombie situation gets tougher.
