So as I understand it, Ady’s revisited editions are basically his idea of what the SEs should have been (& I’m very inclined to agree on pretty much all the changes especially after watching ANH:R) and therefore there wouldn’t be any drastic changes to the story such as killing of Lando. I believe he is simply having everyone on as indicated by a quote of Ady from the “Save Lando” thread posted on the previous page here.
That being said, I am glad to have it confirmed that Lando won’t be making a sudden departure in ROTJ:R. As much as I respect that it’s Ady’s edit, that would be one change to far for me. As long as the end celebration music is replaced with the original music (or at least the current SE music replaced with something more respectful to the OT) and Vader / Ananikan’s force ghost restored to the original actor instead of Hayden that GL shoehorned in there to try and forcibly tie the PT into the OT, I’ll be very happy. One of my most hated changes by GL was when he changed that and changed the music with the extended ending celebration.
