I'm really not either. I actually thought this was going to happen after walking out of TFA. I was hopeful I was going to be wrong, particularly in light of real life events. But there were a lot of clues that led to the idea this was going to happen. Now, I think I'm more excited where this might lead for Ep IX than anything. There's a few ways I think this can go.
The way it goes down, I wonder if we could get "Luke the White." One of the interesting things about some of the early drafts of Return of the Jedi is that both Obi-Wan and Yoda (in different circumstances) are able to come back from being one with the Force. If they can do this and not make it cheesy, I think it'd be pretty cool.
Or Luke stays a Force Ghost. Really, after two films, its time for this generation to stand on their own. Luke, Han and Leia didn't really have anyone helping them out past A New Hope other than Yoda training Luke. But everything was done by the big three. Even though Luke doesn't seem to really leave Ahch-To, he looms majorly over events as does Leia. Rey, Poe and Finn need to do their own thing.
Depends on your definition of shockers. Twists and turns? From the sound of things, yes.
Episode 9 was meant to be Leia's movie, but since Carrie died, I wonder what's going to happen.
It's also been said nothing in TLJ died because of her death.
