I actually think this release schedule is awesome, but only because Rogue One and all the other stand alone movies are not related to the main episodes in any way. I think that's key. I don't think people are going to get sick of Star Wars anytime soon, tossing one movie out a year should work well for Disney, particularly if hey are good films. Things may have to slow down if a movie flops. Time will tell how it all plays out.
