As bad as Disney can be, they have their ups and occasionally seek to make things that can be at least interesting in concept (Tron, Black Hole). Don't forget they also had a hand in making the recent Marvel movies which have ranged from alright to excellent. We also got Pirates from them and while that eventually took a tumble the first was great. I can't imagine the Star Wars situation getting worse now but it at least has the potential to get better.
And like Kman said, there's now hope that the originals can be released in a proper form. Disney generally seems concerned about preserving their past so maybe they'll treat Star Wars in the same way.
