Haven't read about anything on this but as per sir hemi's post these might only contain the Special Editions that were released in theaters in 1997. Many fans didn't agree with Lucas tampering again with the Special Edition movies of the 'Holy Trilogy' (
) release that they resisted buying the previous set. Maybe Lucas released this for them. I might get suckered into this one coz I still prefer the original ending of ROTJ. Haaaay! Star Wars fans are made to suffer, it's our lot in life.
