I agree it's pretty pathetic, but obviously, you know what they're gonna do. When Breaking Dawn Part 2 is released next year, they will have Ultimate Edition DVD's and Blu-rays with all-new extras and collectible packaging, similar to what they've done with Harry Potter. That will be a big money-maker for them.
To be fair, many die-hard fans of the Twilight franchise, particularly the teen demographic, just want the movie. But if you like special features, you might be better off waiting for whatever Ultimate Editions they end up doing in the near future.
