Questions about Summit and Stephenie's website

Okay, so we all have been hearing all these rumors for weeks and I'm just wondering why Summit hasn't confirmed some of them? Yes, they did give information today but still they really didn't give us much.

Why hasn't the New Moon Movie section on StephenieMeyer.com put up the official artwork? I am starting to get worried because last year there were pictures of the cast and the crew getting ready to film.
