Well, George always said that he wanted Star Wars to last long beyond his time for future generations. Selling the franchise to disney is certainly a way to ensure that. I personally don't think that they will ruin the franchise, as Disney is one of the few companies that knows that a good storyline is essential to producing a lasting series of films rather than just rehashing the same stuff over and over with new faces in a way that other companies do. I think it might be a good thing for Star Wars in a way. Disney is more child-oriented, but I'm certain that they can produce something that appeals to adults. Who knows, maybe we'll get to see Tony Stark blast Jar Jar into oblivion. (
Only one question: does this now make Leia a disney princess?
I at least hope that Episode VII will be EU influenced, maybe based around the Thrawn crisis or the reborn emperor. It will suck if Disney decides to ignore EU and go with their own concept; then my hopes will be ruined.
