While the new movies benefit most from the original Star Wars trilogy, I like it when they connect back to the prequel trilogy because it makes the universe feel more "whole". With the great writing of the new movies I expect an appearance by Jar Jar Binks to be worked in nicely.
I picture that old-alien Jar Jar will be a character we sympathize with, given the long and tragic history he has seen and been a part of.
