They really meant it in 1995 that it would be the last time to own the pre 1997 trilogy, up until the bootleg market forced them to include letterbox transfers on the 2006 DVD set. All 3 were the same 1993 scan. The so called original versions. Kershner basically gave his consent to the 1997 edit of Empire. Marquand wasn’t alive to do so. If Lucas was going to do cgi cartoon versions of the films, why would he stop at one movie.
The problem is burying and suppressing the originals.

They haven’t done a new restoration of the OT ever. They telecined a print in 1992 to d1 tape. And have done nothing since. Lucas didn’t want to spend a dime on restoring the original version. He wanted to basically remake the films from the ground up as he always envisioned them. Without totally reshooting the entire trilogy.
