I am glad that Episode 7 is going to be based on George Lucas' story treatment. That makes it all right somehow; we know it will be authentic.
Also, how much do you want to bet it turns out like "Empire Strikes Back" and "Return of the Jedi"- i.e. George is the creative consultant but as he watches the movies getting made, he can't help but start getting his hands in it again.
I think he will be very much involved in Episode 7 regardless what he is saying now.
In which case that would actually be a really good thing- Lucas is best as an equal member of a team.
