Warner has repeatedly stated over the years that a Special Edition DVD will see the light of day. They are starting up these statements again, preparing to have this DVD ready for the 25th anniversary of Blade Runner in 2007. I believe that the many members here will cease to share the DigitalFreak discs when the Special Edition eventually surfaces. As is the case in this community, creators of fan DVDs usually put an end to the distribution of their discs once a retail version is made available. Rikter mentions this any time such a retail DVD appears. There are many Star Wars discs, for example, that he's stopped burning/distributing due to official releases ocurring.
In the meantime though, for those of us who want to see Blade Runner in its best possible presentation, DigitalFreak's DVD of the HDTV broadcast is a big step up from the retail discs that came out during the youth of DVD. You should also bear in mind that many of the people who will get this disc already own an official version of the movie in one format or another (VHS, LD or DVD). It is our appreciation of Blade Runner that drives us to want these DVDs. Once the "Blade Runner: 25th Anniversary Special Edition" is released I will definitely destroy my DVD-Rs of the HDTV DVD and purchase the official DVD.
Right now, the fact that I already own the movie means I should be allowed to have a higher quality version of that same movie. As for the extras, I don't believe any of them are commercially available. This means they fall under the banner of "Titles that have not yet been officially released" and since they cannot be bought, they cannot be pirated.
