I see this reasoning all the time, and really don't understand it. Yes, Blu Ray was put out to deliver the best in sound and picture, but it was also put it to eventually replace DVD. Sadly, I don't see that happening anytime soon when companies are releasing these lazy discs sans extras. I have a Blu Ray player and will probably pick up Doomsday on DVD because the Blu Ray lacks the extra features. There's no reasons they can't throw in an extra disc and add the extra features, or use a 50gb disc as opposed to a 25gb disc, other then being cheap. You shouldn't have to own two copies of a movie, one for the picture and sound, and one for the extras! Superbit did that years ago, and failed. Blu Ray won't take over as long as they make people buy two copies of every movie.
