Guys, this is fantastic news. Phantom Menace and Attack of the Clones sucked majorly, and Revenge of the Sith was better but not great. Handing the movies onto a new director and script writer can only improve things, or keep them about where they are now. It can't make things worse.
Disney is no "more" of a corporation than Lucasfilm or 20th Century Fox, so nothing has changed there. All Disney has to do is hire the right writer and director, and we may conceivably get a Star Wars movie better than anything we've seen since the early 80's. At worst, it's mindless CGI-filled crap, which is all we've gotten from that franchise in the last decade or so anyway.
Agree completely. Whats the worse they do? Make another film that's on par with the prequel trilogy? I certainly hope Lucas' imput as a creative consultant is limited.
