JJ confirms what I already thought what would happen in episode 8 and that is taking the story in a new direction here is the quote
“What was important for me was introducing brand new characters using relationships that were embracing the history that we know to tell a story that is new — to go backwards to go forwards. So I understand that this movie, I would argue much more than the ones that follow, needed to take a couple of steps backwards into very familiar terrain, and using a structure of nobodies becoming somebodies defeating the baddies — which is, again, I would argue, not a brand new concept, admittedly — but use that to do, I think, a far more important thing, which is introduce this young woman, who’s a character we’ve not seen before and who has a story we have not seen before, meeting the first Storm Trooper we’ve ever seen who we get to know as a human being; to see the two of them have an adventure in a way that no one has had yet, with Han Solo; to see those characters go to find someone who is a brand new character who, yes, may be diminutive, but is as far from Yoda as I think a description of a character can get, who gets to enlighten almost the way a wonderful older teacher or grandparent or great-aunt might, you know, something that is confirming a kind of belief system that is rejected by the main character; and to tell a story of being a parent and being a child and the struggles that that entails — clearly Star Wars has always been a familial story, but never in the way that we’ve told here.”
“Larry and I had a bunch of thoughts of where certain things could go and we shared those things with Rian Johnson, who’s directing VIII. He had things that he came up with where he asked if it was possible if we could make some adjustments with what we were doing at the end, most of which we did — there were just a couple that didn’t feel right, so he made adjustments — but it was just collaboration. We’re all fans and friends and supporters of each other, and there’s been no one cheerleading and supporting louder and more consistently than Rian on this, and I feel that I am grateful that I now get to take that position for him.”
this part right here show that johnson is prob really branching the story outward...
