Even if they’re sitting on it until 2020 and it’s just a matter of “when” and not “if” (they would never tell us anyway), I still think some kind of open letter to Lucasfilm is a good idea.
We could explain to them in very straightforward terms that we simply want the same treatment given to the Star Wars saga that films like Close Encounters and Blade Runner have already recieved.
If it’s going to be three more years, they might as well take that time to get it right.
