While Spielberg directing "Jedi" would have been fantastic, the real undoing of the awesomeness that would have been "Jedi" was Gary Kurtz leaving (being fired?) as producer. After that Lucas went on a big power trip and threw out all the outlines he and Kurtz had banged out together after ANH, and started from scratch. And look what we ended up with.

I really, really, really want to read the original ESB and ROTJ outlines that were written after ANH ... but I don't think it'll ever happen, sadly.

Well, I do have a book called "The Star Wars Trilogy Annotations" which includes all three screen plays plus added notes about original rough drafts, like how Kashyyyk was originally in place of Endor and that the rebels got help from the Wookie natives, about how there were two (or possibly more) Death Stars being constructed and that the final battle between Luke and Vader was going to take place on Mustafar.
