My Theory for Book 5 Ending

My friend and I have been talking about how WaT and what will become of all the main characters. We think Dalinar won't be to necerssarily "defeat" Odium's Champion but more seal him away along with himself, Kaladin, Shallan, and the other Radiants. And when book 5 begins, there will have been a very large time skip to a more modern society where people worship them as basically the new "Heralds."
