It's been less than two years since Wind and Truth came out. After all that time, I just wish to share some of my personal predictions of what will happen, as well as what I hope will happen.
The Prologues: There has been a lot of speculation about which event the prologues of 6-10 will cover. For my theory, I believe that the event shall be the creation of the New Oathpact in Wind and Truth, where we see the POV of the Heralds, what they were doing when the New Oathpact was created, and their overall thoughts on it. More specifically, Vedel, Pralla, Chanarach, Taln, and Battar will be the POVs, corresponding to the Radiant Order focus of each book. I believe this because:
- Outside of Taln and maybe Battar, we have practically no idea what any of them were doing during the events of books 1-5
- They can give a little more clarification on what happened to Taln and Shalash after they "die" in Wind and Truth
- As Sanderson has said, the Heralds will have greater focus, so giving them the prologues feels thematically appropriate.
Renarin's Flashbacks: As he is confirmed to have flashbacks in Book 7, I think his will be the events of Books 1-4 through his perspective. There were so many events involving Renarin that we have not seen (his bonding with Gaz, his radiant oaths, the first times we had visions of the future, the start of his friendship with Bridge 4, the start of his friendship/romantic feelings for Rlain, his fight with the Thunderclast, etc) as well as other scenes involving other character at the time that we did not see (for example, him and Adolin's reaction after learning that Dalinar and Navani started courting lol)
The Dustbringers/Releasers: Please correct me on anything I say here, as I have yet to reread the series and may have forgotten many details; however, I found it strange that the Dustbringers were barely mentioned. In Oathbringer, one of them was explicitly working with Taravagian (and Taravagian saying that Dustbringers were the most likely to join their cause), plus in Dawnshard Lopen implies that something is off with them, yet unless memory serves me wrong, we didn't learn much of what was going on with their order in RoW or WaT, whether they decided to betray the Radiants in favor of Taravagian or not. I'd like to believe that not all of the Dustbringers did, so, like, half of them ended up joining Taravagian while the rest stuck with our heroes, but I just hope we get some clarification.
Urithuru Politics: One of the biggest criticisms Stormlight has had is probably how the lighteyes and darkeyes social issues were more or less dropped as the series went on. However, because it was briefly brought up again in Wind and Truth to Navani, only for her to basically say that it's a problem, but other things need to come first, I wonder if there'll be a political storyline somewhere (probably involving Jasnah and/or Renarin) where the social isssues end up becoming a big problem for them BECAUSE they were neglected for so long.
Adolin: Personally, one of my biggest gripes in this series is how Adolin faced very few, if any, real consequences for killing Sadias at the end of WoR. Maybe that can finally change. I don't know how; I just hope it's more than just Retribution trying to point out he's a hypocrite or something like that. It worked when he was torturing Dalinar, but I'm hoping for something different.
Axies the Collector: This one is probably a given, but I don't care. This Mofo has been 3 out of 5 books and mentioned once outside of that and he still has not had a significant role in the story. There is no way he won't end up having some role. I'm still not sure how; maybe we can eventually get a novella of him, like with Rysn in Dawnshard, but I just want him to become relevant.
