RotJ's 5.1 is nearly complete; there is only one edit left to finish. I hadn't anticipated doing it, but I decided to replace a short section of the 1993 mix (Luke defeats Vader) with the 35mm stereo, because I prefer the way it sounds with the music carrying the scene as it does in the original mix. The LFE channel is all done, so after I make the final edit I'll send it off to Satanika for upmixing as before, and it'll be good to go.
Definitely looking forward to this set . . . ;)
