Variety had an article on why Twilight should be a blockbuster.  They also had this to say:

“While Oprah didn’t jump at doing a “Twilight”-dedicated show, Ellen DeGeneres begged for it — which was fine with Summit, as she has a younger audience. Pattinson and Kristen Stewart, who plays Bella, are booked on the talkshow circuit, including the “Today” show. In November and December, more than 50 magazine features are planned, including Vanity Fair.”

The stars are also doing the press junket rounds this weekend, so look for lots of Twilight interviews next week!
