Maybe you guys don't quite understand how this works.
Disney now owns Lucasfilm, but Lucasfilm is the same as it was before. It just had a new CEO now that George is retiring. They won't be handing scripts of any kind to Disney because Disney isn't making Episode 7, Lucasfilm is. Sure Disney now can have some creative control, but Marvels is still making its movies as opposed to Disney making them. Sure Disney asserts a bit too much control at times, but not very often.
This movie(s) will succeed or fail because of Lucasfilm, not Disney. They already have treatments for the movies that George wrote. Here's to hoping someone else will handle the dialogue.
