It will be necessary to have a Burning Crusade CD/DVD and a Burning Crusade authentication key in order to play The Burning Crusade expansion. There is content on the Burning Crusade CD/DVD that will need to be installed that is not included in the patches we have recently released. Each account (in the event multiple are owned) will need their own copy of The Burning Crusade expansion to install the additional content, and be upgraded with the included authentication key.
*Update*
Just to clarify things a bit: You will need the Burning Crusade CDs/DVD to install the expansion, however you will still be able to launch and play the game without needing to have the discs in your drive. Essentially everything will be as it is currently, where you will only need the discs for installation of the game.
