I was just wondering, do you guys know how you're going to present the audio on these three films? I'm curious to hear the theatrical soundtracks: 70mm 6-track, 35mm Dolby Stereo, 35mm mono*. Are you thinking of making DD 4.1/2.0/1.0 mixes, or perhaps a PCM "complete" mix with every missing bit reinserted, like C-3PO's tractor beam dialogue, Stormtrooper blast door line, etc.?
From what I've read, the Dolby Stereo mix was used for the 1985 CAV pan-and-scan laserdisc. I know there's a mono mix (taken from a 1977 bootleg tape) floating around somewhere; not sure about the 6-track. I've heard it was folded down to 2.0 Dolby Surround for 1993 Definitive/1995 Faces LDs. Others have said it was PCM.
I'm not too worried about the picture quality; looks GREAT thus far.
