ROTS is probably the least important of the pre-Disney films to get scanned, as the one difference from the DLP theatrical to DVD was an optical wipe that was restored on the BR, and Schorman has made a theatrical reconstruction using the BR wipe with the HDTV video (to remove the few minor BR changes) and paired it with the theatrical DTS audio, so we have ROTS in its theatrical form in 1080p already.
Having said that, it would still be neat to have 35mm scans of every Star Wars film!
Plus, does anyone know if there were any 35mm-to-DLP differences for ROTS like there were with AOTC?
