You're trying to equate different scenarios to create a precedent to justify cynicism that isn't warranted.
This movie was specifically designed to close the "Trilogy of Trilogies" that George Lucas had designs on doing off-and-on for years and years, and it shows.
Believing that Lucasfilm is going to negate that is, at this point, being cynical for the sake of being cynical.
Yeah, we'll see. I'm willing to admit when I'm wrong. Are you?
