One thing that I dearly hope is addressed and resolved by the end of this new trilogy is the relationship between Luke and the Force ghosts of Obi-Wan and Yoda. They HAVE TO address it in a very
robust manner. If they don't, it'll be an enormously cowardly move on their part. Having two of the most powerful Force masters ever, being able to mentor Luke and freely converse with him (Obi-Wan's spirit was just casually walking the swamps of Dagobah!) - man, that's a huge problem for writers. It also begs the question, "Well, shouldn't Anakin's Force ghost be there mentoring Luke as well?" Yes. Yes it does.
They MUST eradicate these ghost-Force-Masters as they provide for far too many opportunities to generate huge plot holes. Luke is at a tremendous
advantage with these Force ghosts milling about...
"Dodge to your left Luke!"
"Forward roll you must!"
"Son, there's a bounty hunter posing as a barman in that cantina, and he's poisoned an umbrella garnish for your iced Tantooine Tea. By the way, stop drinking that swill Luke. The artificial sweeteners will eat holes in your brain..."
We know from the end of Ep. III that Qui-Gon Gin's spirit TAUGHT Yoda about these Force ghost intricacies
! That Force Ghost Trio would give Luke an enormous advantage in everything that he'd ever encounter.
And if Leia does die in some way, and regardless of the circumstances and distance, Luke would HAVE TO KNOW about it because of his connection to her. For them to write anything otherwise wouldn't align with what was established in the prior movies.
Maybe we'll see the command bridge of Snoke's gigantic star destroyer, and he's pacing back and forth in his golden robes in front of several figures wearing gear that looks technologically advanced, and quite intimidating. As the camera pans up the legs of Snoke's dreadful bounty hunters, we'd see the faces of Dan Aykroyd, Bill Murray and Ernie Hudson!

I don't care how they do it, those Force ghosts have to get busted...!
