“After dissapointing movie ticket sales, it seemed that Joss Whedon’s Serenity would en up as a failure in the books. Think again. Over 2 million DVDs sold, plus rentals and TV rights add up to more than $60 million. Could this convince Universal to get a Special Edition out? or even a sequel?”
Certainly, there’s an HD-DVD version scheduled as well, so the story is not over on that account. I do not know if there are features to the HD version that are not in the already released DVD. However, this is certainly good news.
