To add to the list, it feels to me that the conclusion to Orochi is not just simply going to be the cliche "you die because you evil". I mean there will be that, but with it we will perhaps get our first glimpse into the history of Wano.
It could be where Tengu reveals a lot of it (if he's Sukiyaki), because Orochi getting his comeuppance should be for everyone to see one way or the other. I think the Korozumi clan have been the way they're portrayed to be way before the daimyo assassination incident.
Interestingly, Kurozumi clan is the only one which doesn't have a moon(-tsuki) suffix in it. With so much symbolism involving the moon in this arc, it really does make you wonder.
I've also probably discussed this earlier, but Jinbe saying that the minks turn into sulong because "deep buried memories of a distant past" awaken inside them is extremely intriguing. Maybe it's just a homage to Toriyama's Oosaru transformation, but I definitely have my eye on that (especially with Zunisha here now)
So all in all, this little exposure on the clans on Wano will lead us into the big Kozuki plotline which will then be shortly addressed by Kaido during his fight with Luffy. There are at least 6-7 panels of him just begrudgingly referencing the Kozuki in a way, which clearly make it seem like they go beyond his enmity with Oden.
I think it'll be at this point, that'll get major bombs - Kaido's race, ancient giants (their connection with Wano?), god valley incident (hyping Xebec's relevance for the future), why Wano is special, why was Wano needed as the trigger to the final war, relations to Yamato's mother and probably a lot more.
What's crazy is that this just Kaido's side of things, now we have a relic of the past in the form of Zunisha walking right towards us, which opens up even more room for exposure.
The Zoro stuff definitely looks interesting, there will definitely be a prevalent theme on death/remembering the dead in the upcoming chapters with the citizens now ready to fly those lanterns. You have to wonder if some of this will also begin to address where Kaido's philosophy on death stems from.
Should be some really exciting months ahead of us, at least in terms of getting a lot of juicy lore drops.
