I think most people will be impressed by the update. There will be a huge re-ride-ability factor for this thing. I understand that it takes place, as said above, between Empire & Jedi but visits locales from all six films.
Just as everyone keeps saying to give that fountain show with no Walt in it at DCA a chance, this should also be given a chance! It looks really fun to me...while there are things that I'm sad about (Captain RX) there are things I'm crazy happy about (Boba Fett).
Star Tours needed some new legs & this re-do will give it just that!
