The new Bright Falls website is finally online. BrightFalls.com

Although the videos will be avaliable on Xbox Live April 26th, they should appear on the website the following day.

EDIT: The site includes the videos everyone was expecting, as well an additional audioscape and pandora integration. Interestingly there's also a section called Alan's Story which appears to have additional clues about what led up to the events of Alan Wake. New clues are being unveiled as the "episodes" air.
