I was hoping for more changes, to the ships and stuff. Think about how many changes there were to the various ships between the Clone Wars and A New Hope, and that was only 25 years or so. This is 40 years after ROTJ. I think there should be more technological advancement.
It only makes sense if you think of it as Episodes 1-3 representing a peak in the galaxies centuries long stretch of a more consumer-oriented peacetime technological trajectory, with considerable importance on a balancing of form & function that makes beautiful fast ships, clothing and weapons...
and then the soul-crushing hopeless oppressive militarization of the Empire (whether for 20 years or a thousand years as originally stated) sucked the fun and joy out of everything, derailed the aesthetics, smashed or repurposed everything beautiful as people do in wartime, and replaced it with armies of pure industrial machinery at ENORMOUS cost.
...such cost that a mere few decades later, everyone is still cleaning up the mess and trying to rebuild basic functioning society, & building neato designer weapons takes a back seat, so all they really have handy are the old warbirds yet.
...OR MAYBE, THEY'LL "REBOOT" THE PREQUELS, destroying the originals like Lucas claims to have done to the unedited Episodes 4,5,6, or simply considering them and the clone wars non-canon fanfiction, and finally create new prequels that actually make sense in the star wars universe, where the things look like they look in that galaxy, the empire was more than two guys' brief failed power grab, and did reign for a thousand years, not twenty, the galaxy wasn't taken over by flimsy android comics, the force is universal and not trivial because there are no midichlorians, Yoda is a powerful master of it that doesn't need a lightsabre, and not just a green bug that spins around and can barely lift a falling beam, ETC ETC ETC.
Disney spent a LOT of money buying Star Wars, once they make a few sequels and Lucas passes away and isn't around anymore, I'd put money on those horrendous, hated prequels being replaced by better ones.
