I might eventually see the upside to all this, but right now I'm just numb with shock.
Lucas put everything he got out of the first Star Wars film to build an independent film-making empire up in Northern California, taking all the merchandising rights Fox (in what proved to be a stupendously short sighted move) gave away to him in his original contract. The difference between Star Wars and all the other film series owned and beaten into the ground by other studios, was the rights were owned by one man. And he made them the way he wanted to, with no studio bureaucracy breathing down on him. It made the films special events when they came.
....And now - the empire, the rights to Star Wars - it's all owned by Disney.
The immediate up side for George Lucas - aside from pocketing a few more billion - is now all the haters who can't give up the littlest change can go complain to Disney from now on about Who Shot First etc.
If you've been wanting him gone from the saga, well congratulations. You're succeeded.
