At least with Lord of the Rings you know you'll have your choice of either version soon enough, by the time Hobbit comes out. With Star Wars (on top of having to beg to get the first versions at all) we have this totally annoying secret mystery of what and when the eventual set will be. Multiple versions? More changes and if so, what are they? Coming out next year? Three years? "Oh, we can't tell you that now! It's a secret, and someday if you're really good, we will bless you with the knowledge."
