hairy_hen wrote this in another thread, but I wanted it here as well.
"It would be kinda neat if this version included the 35mm stereo, mono, and 70mm 5.1 soundtracks all together, so the complete theatrical auditory experience would be available on one disc. ;)
For Empire and Jedi, 70mm recreations aren't strictly possible, but the '93 and 5.1 soundtracks on the previous versions already sound great. I've been considering doing small revisions on Empire, to substitute the hacked up music cues with how they are in the SE and add the missing snowspeeder sound, but those are only minor changes. Jedi I believe I am quite satisfied with as it is."
