If I had one criticism about that article, it would be that the over-merchandising of Star Wars is nothing new ... Return of the Jedi's use in advertising was just as nauseating as Sith's (C3PO cereal, anyone?).
Oh, and the Henson bit is wrong. Henson himself really didn't have much/anything to do with Yoda ... most of the people who were involved are still alive and kicking.
