Well, Lucas always said that if he wanted to do something different than what the EU said, he was going to do it. At that point, it would be up to the EU authors to make it work. But this guy just seems sad.

I met a guy at a party once that was kind of like this. He was an author that was trying to write prequel stories to some things he'd written himself and he said it was very difficult to do. He used that as evidence to say that Lucas must have had the whole thing planned since there were to many similarities for it to have "just worked out". His biggest example was that in the OT, R2 is almost always with Luke and in the PT, R2 is almost always with Anakin. I tried to explain how that would be quite easy to do in the prequels, but he wouldn't really have it. He was convinced that everything was planned from the beginning because otherwise, it was just to hard to make it all work. This was just after ROTS came out, but I doubt that that changed his mind. I even said "but he's not making it work!". His response was that he was and it did. He even cited 3PO and R2's actions on Tattooine in the first movie as perfect examples of how it was planned from the beginning. Of course, I think those things just happen to fit, but only after ROTS came out and 3PO's memory was erased.
