Do you think "Uber" will be dealt with in one trilogy?

It's been rumored that Andy Serkis' character in the Force Awakens is code named "Uber" in the drafts and that he will serve as the Palpatine so-to-speak of this trilogy. Now the question is will he be dealt with and defeated come the close of episode IX?

Before you say "the story won't be complete if he's not.", the Emperor originally was not to be defeated until Episode IX in a show down with Luke and his sister (who was no originally Leia). The decision to kill him off at the end of Jedi came relatively late into the production, after Gary Kurtz left the project, and Lucas decided Star Wars had taken too big a toll on his personal life- making him want to be done with it all together. Jedi was supposed to end with Luke and Vader having some sort of a personal resolution (as this was the meat of the story and still is, not the defeat of the Empire), Han was to die, Leia was to be left with a great burden as the Queen of the reformed Alderaan, and Luke was to walk off into the sunset to search for others to rebuild the order.

Given that Disney clearly doesn't have Lucas's "let me be done already" mentality, is it possible we could see an ending like this, and that the greater evil behind Kylo Ren will not be a huge present until perhaps Episode X?
