We now know Episode VII will start with an original story. My speculation is that the "A long time ago..." could be the master trick of the future of SW movies. The old republic spans over 250 centuries, and the post-legacy era is still a fuzzy vision. Even if they are going to make sequels, or post-ROTJ movies, does not mean the action takes place at a "when", we know from the EU. What if we dont know exactly when the Episodes VII VIII IX, sidestory movies and such take place ? What if that was the trick ? To not know. Except, maybe, in the end of the trilogy. There are speculations they're going to make Phase-One sequels SW, a la Marvel. That's ok by me. All i want to know is if the last movie will fit without breaking the EU too much. N thousands years in the future would be great, not knowing when exactly.
