Star Wars has six whole movies and two shows worth of material, plus whatever new stuff is coming out. Sets we could get/could have gotten include
Cassian and Bohdi (in the Rogue one wave)
Krennic (also in Rogue One)
other clone trooper variants
New Trilogy Luke
Yoda (is there a reason why SWC can't have small sets?)
And that's just what I could think of off-hand. You get the idea.
*sadly, this'll likely never happen; Jar Jar could be an interesting set. I could see it including tan protector feet, for example.
