The Elder Scrolls V: Skyrim - Dawnguard DLC Released on Xbox 360

It's been a relatively long wait for Skyrim's first set of DLC, but today Xbox 360 gamers with $20 to burn can finally enjoy Bethesda Softworks' ambitious Dawnguard add-on. Head on over to the profile page to queue your download, then have a look at this post on the official forums to learn how to get started once in-game.
Dawnguardâ„¢ is the first official game add-on for The Elder Scrolls V: Skyrim® - the 2011 Game of the Year. The Vampire Lord Harkon has returned to power. By using the Elder Scrolls, he seeks to do the unthinkable - to end the sun itself. Will you join the ancient order of the Dawnguard and stop him? Or will you become a Vampire Lord yourself? Featuring an all new faction questline and locations, the ultimate choice will be yours.
It's really a shame that the rest of us have to wait 30 more days, but I guess it's just business as usual.
