Likewise, discussing how the fact that the Sith Destroyers were based on the old ANH/R1 types, and not the newer ESB/ROTJ versions means the Death Stars make no sense; if Palpatine had already invented a ship-sized superlaser before the ISD-II was rolled out around the time the first Death Star was completed, why finish the battle station at all and not simply use his backup fleet to maintain control of the galaxy in the first place? Then I thought, it’s weird that the visual effects team could make a Cloud City model for one shot, but wouldn’t make a digital version of the ESB destroyers when they were far more prominent. And, while I’ll have to wait for the home release to be sure, those cannons looked like the ones from the FO dreadnaught in TLJ. And, oddly, the Art of TRoS book that was supposed to come out today has been delayed three months. Which makes me wonder if the closing battle had some major changes, or was added entirely, late in production, explaining why the making-of material would have to be revised, and why the Sith fleet was a kitbash of models they already had.
