I seriously hope that the sequels explore new worlds, new alien life forms, new ideas, new characters, new personalities, new spaceships, new weapons, new friends, new wars... in short, expand the universe, stop shrinking it. I want to leave the theater with MORE wonder, not less.
That's what Star Trek is meant to be for.
Exploring an expanding universe.
Star Wars is space opera.
It's conflict focussed on a series of characters who are to some degree related to each other (like real Earth Opera without the singing).
It makes sense we would see Tatooine and Coruscant more than once because that is where one half of the 'family' lived and where the other half worked.
