Another thing to bear in mind regarding the future of SW is that, based on what can be pieced together, virtually everything that GL had put together about the Prequel Trilogy before he sat down to write it in the early 1990s was already publicly known. Despite a few contradictions in the details regarding the Emperor, the bare bones of how the Republic collapsed & became the Galactic Empire was in the prologue to the novelisation of Star Wars, published in 1976, there for all to see before the very first film had even been released. The volcano duel between Obi-Wan Kenobi and Darth Vader was outlined in GL's interview with Rolling Stone, even before it was determined that Darth Vader was once the father of Luke Skywalker. There was further elaboration about Anakin Skywalker's fate in the novelisation of ROTJ, along with what little story existed regarding Mother Skywalker and how baby Leia was taken to live with Bail Organa & his wife on Alderaan (largely abandoned), some of which even made it into the shooting script of ROTJ. Beyond that, it doesn't really seem that GL had much else thought through (he admitted to throwing a few ideas for the PT out & starting over). For all the poring over the OT & tidbits in 1980s articles that went on during the 1990s in a desperate attempt to anticipate just what would happen in the new trilogy, it seems that everything that had ever really existed in the mind of George Lucas regarding Episodes I-III, we knew already. When GL began writing the PT for real, he was starting essentially from scratch, with a few plot points he was stuck with, and which were well known. This was a series of films he was far more committed to than the vague Sequel Trilogy of Eps VII-IX - they had been created as part of the backstory to the films he was working on, and were bound by the events of the OT. The Sequel Trilogy, however, owes nothing to anyone, and GL has been denying its very existence for over a decade. Just what the "outlines for 7-9" he claims he has and is giving to the new writers could be anything, and given how little really existed for the PT by the 1990s, it's pretty ludicrous to think that there's ever been much for this bastard trilogy of SW at all, let alone anything relevant that still exists. We've picked apart every detail we could in other threads in a desperate attempt to figure out what it might have been about back in the late 1970s/early 1980s, and it looks as if anything for the ST ever did exist, developments in ROTJ & the PT sent them straight to hell (the 'Other' mentioned by Yoda in ESB, other Sith Lords etc). What little might remain we most likely know already - rebuilding the Republic, passing on what you have learned, Jedi Knighthood, moral & philosophical questions. That's probably everything that still exists regarding the ST.
