I'd really like a boxed set of six movies, just so I can have my closure and never buy them ever again. Perhaps that's why we'll never see them all in one box - customers like convenience, but profits can be made from confusion. We'll probably see a DVD boxed set of all six just as DVD becomes obsolete and HD versions (all flavours) are being pushed. As for extras, I really love the fan made stuff, especially DM, BE, RTJ ... now that's convenience!
