The opening of RotJ is still up for discussion. It will either be Dagobah, Tatooine, or Palpatine's arrival on the Death Star. The ESB opening was always rather weak, inspiring the Death Star arrival scenario. It's Star Wars tradition to open in space with a ship of some short, but starting 2 films with back-to-back arrivals at the Death Star may be too much though, so we'll see.
This is just a general comment- I find it surprising that so many people find the opening to ESB to be weak! I love the slow open. The film has such a nice and steady pace, and the shot of the probe droid always makes you go, "hmmm, now what the heck is this going to be about?" Is this really the general consensus?
(This post shouldn't be taken as any criticism of the project- I'm all for any and all changes. The more the merrier).
