Aha, thanks - so the free hoodie (and they're really nice hoodies!) happened already. The promo page is still pretty neat, though, and a quick perusal of the javascript indicates there may be some more hidden material in there somewhere.
Yes, they sent hoodies on premiere night to the first 509 people that reached the end sign-up page. Very cool of the marketing team and everyone involved.
