Just found this at the reliable DVD news source The Digital Bits which tells us that the upcomming release (or is it re-release) of Blade Runner: Directors Cut will be a single disc with no extras (as the old release).
… The studio has officially announced the re-release of Blade Runner: The Director’s Cut on 9/12 (SRP $19.97). This is a single-disc release, with no new extras, but you’ll be pleased to know that the video has been completely remastered with a brand new anamorphic widescreen film transfer. Keep in mind that a much more elaborate multi-disc Blade Runner: Ultimate Edition is currently in production for release sometime in 2007 – that is CONFIRMED. This disc is really just designed to update the original Snapper case release (one of Warner’s first EVER releases on DVD back in 1997) in the meantime.
Update 2006/07/27
The audio will be Dolby 2.0 Surround, like the original release.
And that’s the truth (atleast when it comes to the quality of the old release) and I think that I might skip this release since I already have the old Directors Cut and most certainly will get the upcomming 2007 release.
