I've never planned on replacing my original DVD movies with Blue Ray. It's not worth spending more money on something I've already have even if the Blu Ray has more enhancements. The main thing for me is watching the movie and a DVD provides good quality picture already. Unless of course, if it's a movie I own on DVD and the Blu Ray version has extra features such as extended or deleted scenes and documentaries etc, then I may consider replacing that particular movie and buy the Blu Ray version, it really depends. However, I own a couple of Blu Ray movies which I don't have on DVD and the experience between the DVD and Blu Ray is not very significant, just the high-definition is mainly noticed. So I would not really plan on replacing DVD movies.
