Harmy, if Disney does properly restore the Original Theatrical Unaltered Versions of The Star Wars Trilogy and release them on Blu-Ray how would the Despecialized Editions compare to them?

No way to know until they're actually available for scrutiny, but if I were a betting man I'd say that the official editions will have a much higher bitrate and be free of the (mostly very minor) compositing artifacts that remain in the Despecialized versions, but will have pretty sloppy color correction, in keeping with past releases.
