It would be nice to get a formal Bungie response if purchase of the Disc or DLC will allow more than one console user to play the game. DLC Usage Restrictions states, "You can use this item on the first Xbox 360 console you downloaded it to. Access to this item will also be granted to all users on this first console." At this time, only one Xbox 360 user is being allowed, and M$ support says that is "how it is".
