"Dear Call of Duty Customer,
If you're experiencing difficulties accessing the Call of Duty World at War Beta, beginning tomorrow morning, Tuesday, November 4, at 2:00am PST you will be able to access the Multiplayer Beta. You will no longer need a beta code to access. Simply enter the Xbox Live Marketplace, click on "Game Demos" and locate Call of Duty World at War to download the beta. If you have further issues regarding the beta you can contact the Activision hotline at 1-800-229-3399.
Thank you,
GameStop Customer Service"
Copied from the Call of Duty forums, there's loads of people complaining over there that it's not up yet but apparently the developer hasn't menitoned anything about the beta going public, only GameStop.
