They should give the option for the DLC to be either individual download or bundled as a group (aka exactly as it is now). I'm sure there are a lot of players out there, like myself, who don't like the multiplayer enough to spend any money on it, but wouldn't mind shelling out around $5 for the Zombies (or vice versa).

Keep the bundle at 1200 MS, but charge more % wise for the individual downloads to encourage players to get the bundle.
