Here's my take: I feel this is a good thing for Star Wars fans everywhere.
1) Like I said above, I like the prequels. Although it took a few times watching them to appreciate them. I also had to read the books to get some of the back story (for all who dismiss Phantom Menace, read the book. It makes the movie much much better). So, even though I'm a fan, I don't feel they were as good as the could have been. Lucas was balls deep in the prequels. Part of what makes Empire so good and Jedi good is that Lucas didn't direct those movies or write those screenplays. Still his stories, someone else's vision.
2) Disney has a damn good track record with other licenses. They bought Marvel, and those movies, while not for everyone, are still good movies. They are taking great care with the Muppets and staying true to Jim Henson's "brand". The Pirates movies, although not my cup of tea, have fans just as crazy as we are. Almost every Pixar movie wins awards because they are good movies. The Tron re-boot is actually not terrible.
3) Look how much freaking Disney toys and merchandise is out there. If there is one thing Disney loves, it's money. I don't see us having any problem getting SW toys or collectibles anymore. I think Disney is going to go into Hasbro and say "Get that product out there". And if Hasbro can't do it, Disney will find another manufacturer who can. Remember when Tron came out? The stores were overflowing with figures and light cycles. I still see them in the clearance aisles.
4) NEW STAR WARS MOVIE(s)!!!! And episode VII (and VIII and IX hopefully)! Lucas said he was never going to make these movies. My question has always been "Why not?". Give the fans what they want. And we want more Star Wars. Every one of you will go see these movies. Like Penter said, we've been waiting for episode VII since 1983. For whatever reason, Lucas said no. No one asked for the prequels. And to be honest, he made the most feared villain in a galaxy into a whiny b*tch. Mark Hamill has said he's reprise the Luke Skywalker role. I'd love the chance to see Mark Hamill as a full fledged Jedi master.
