It seems that George put a year or so into planning what comes next...

I have no problem with Lucas writing the outline or the general story for the ST, as long as he stays away from directing and dialogue.

Michael Arndt is writing Episode 7, while JJ Abrams is directing Episode 7, and Lucas is more involved in the macro part of Episode 7 laying the ground work for the Trilogy. That worked best in ESB, where Kasdan wrote the script, Kershner directed the movie, and Lucas created the overall outline of the movie.

I only wish Lucas would have done this with the PT, and it would have been much better.
