If we're lucky it will be a big bandied about process resulting in a simple presentation of the 35mm general release editions.
If it actually happens, we're probably talking about conforming a new 97SE scan to the original cut with probably the Dolby Stereo track for each-probably then upmixed to 5.1.
But...if we get really, really lucky..a full-on restoration process could be underway, akin to what the majors do on their big titles like Sony and Warner. Robert Harris has even offered his opinions on several occasions.
Heck if Universal can start actually doing this stuff correctly from time to time, there's no reason why it can't happen.
But the big problem is that even if this does ever happen...no one is going to know, understand or even put the time in to get just how many variants, audio mixes and tweaks exist for the OT. I've spoken to many about things like for example the SW mono mix and they look at me like I'm nuts. How many in the loop do you think have even touched upon color consistency on Death Star interiors or garbage mattes or any of our usual topics?
