1. The Return Of Palpatine
The big bad of Star Wars may not have achieved his dream of true immortality in the films, but in the EU Palpatine actually succeeded at transferring his essence into other bodies after his death, even temporarily resuming his position as Emperor. So far, in the canon, he remains dead, but the question is, will he stay that way? Snoke may be cool, but nobody surpasses Palpatine when it comes to sheer, absolute evil. How awesome would it be to discover that all along, the First Order had been trying to resurrect the glorious and ruthless leader of the original Empire, either by cloning or by supernatural means? Or that it happened between trilogies and was instrumental in the fall of Kylo Ren. Combine that with the fact that Shakespearean actor Ian McDiarmid does such a mighty fine job of bringing Palpatine to life that he has us practically glued to the screen, and this doesn't sound as ridiculous a proposition as it first seems.
