I think there's far too much panic over this. Lucas hasn't been on the ball with the Star Wars franchise for over a decade. This is one of the best results we could have for long term Star Wars survival. Disney know how to make sure things last and remain talked about and consumed for years to come. On top of this, considering they pegged Joss Whedon for Avengers, they clearly know how to pick the right person for the job. People thinking Disney are going to do suddenly change the franchise in some ridiculous manner are just panicking.
Yesterday don't mean SHIT.
