Bethesda’s announced that those who wish to participate in the Xbox 360 beta for Dawnguard should sign up here. Applicants need a registered account on the official forums, so make sure your forum email address is up-to-date. Bethesda will be selecting applicants in about a week. Players accepted into the beta will receive an Xbox Live code to redeem Dawnguard. The beta is the full version, and those participating will not have to purchase the content. Dawnguard is out this summer as a 30-day exclusive Xbox Live for 1600 MS points, after which it will release on PC and PS3.
