Great link and article. A few thoughts
Joe Johnston really created the entire design of Boba Fett. George basically just came up with the name. Its really fitting that he will direct the film. I wish the article had brought that up.
Luke Skywalker having kids goes completely against the prequels and how they thought of the Jedi. If this is true then Luke is either saying the old rule stunk and he isn't following it or the creators are abandoning the prequels completely.
On that note, the voice of Fett in the Special Editions is Temura Morrison. Now if they change that, its not going to fit with the Special Editions which means...
Original Untouched Versions to be released. This could be an indicator.
