So this seems a perfect point to enter into the forum life (had an account for ages, never used it).
Brandon said in that reddit post that the primary character who was not in Part 4, but is now, has fewer chapters in all the parts. I don't think that's
Shallan. She has lots of POV as it is, ending at a big scene.
So I'm 90% sure that Shallan will miss Part 2 as a POV, while Kaladin has a decreased presence in all the first three parts. Hence I predict that no parts will end
with a Kaladin cliffhanger until the book' end.
