One: It is the most anticipated movie of the year. I think we can all agree to that, even if Du aren't a huge twilight fan.
Two: With the Eclipse promotion not even lifting off yet, the trailers, teaser posters, Mehr people are excited for other movies. For example: Karate Kid, Avatar, etc. The Fans of the Filme and not the Bücher don't have anything to go off of.
We know the Eclipse teaser trailer will be coming out soon, but I think they waited too long. They need to start releasing the trailers to restore the anticipation. There's already anticipation from the twilight fans, but what about the rest of the audience? Summit needs to learn about promoting and the process of movie making. They aren't doing a very good job. And, they can't always count on the twilight Fans to bring in the big bucks, even if they are reliable for going Mehr than enough times.
I think it will. Look how well New Moon did over Twilight...and I think Breaking Dawn will do even better than Eclipse. No one can seem to get enough of the vampire/wolf saga and no one can seem to get enough of Robert Pattison oder Kristen Steward oder Taylor Launter.
