Live teaser for unknown Alan Wake project

As mysterious as the game itself, this live teaser for Xbox 360 exclusive thriller Alan Wake has hit the web. Speculation would have us believe a lot of things: maybe a short film, Xbox Live episodes, the continuation of the mini-series Bright Falls? Or maybe a teaser for the first, July-bound DLC for the game, The Signal? Just post-release marketing for the game? I give up.

Whatever it is, it should be revealed next Wednesday.
