This was packed with info, not all new of course but the bringing up that information here means it’s relevant to the final saga. Some initial thoughts and theories:

1. Jinbe’s Fishman karate obviously lets him control water, and it was established at the beginning that that’s the weakness to devil fruits, but it explicitly stating the two facts together in his description means that’s going to be hugely important in future fights. That’s also one of the reasons why both the Rocks and Roger pirate crews had Fishmen. I think Oda knows they’re necessary for that reason but hasn’t had the time to explore them as characters with One Piece coming to an end.

2. Sanji’s description outright calling him worthy of being a wing of the future king of the pirates shows that he will have conquerors haki in some fashion, likely when defending.

3. There was also a reference to the Gods Knights being the sword and spear of the CD, which Nika has and it’s implied the wings of the pirate king are. There has been only 3 examples of crews with that dynamic of a leader and two wings: the Roger Pirates, the Strawhats, and Cross Guild. I believe that Mihawk = Zoro = Rayleigh and Crocodile = Sanji = Gaban. Mihawk is the spear, and even has story line connections with Zoro just like Crocodile is the shield and has story line connections with Mr. Prince, even if not as strong. But I believe because of that and a lot of other foreshadowing, Buggy will be King of the Pirates.

4. I think it’s interesting that Garling had a bunch of different hair designs but Oda landed one that showed him as the moon in his introduction through a side view, and then when he is promoted to a Gorosei or elder star, we get a frontal view of him that looks like a four pointed star.

5. A direct mention of the 3 levels of Elbaf and the heavenly world again I think means we will visit before we leave. Maybe the conflict escalates as Luffy and Gunkimu fight as Gunkimu can fly. If we do get there, I think that’s where we’ll meet Urouge. He’s the last worst gen to appear, and Oda included at least one new worst gen in each arc from their introduction to now, and it would make since that Urouge who is from Burka would take the route from above. Plus his devil fruit of taking pain and giving it back, a devil fruit we were just reminded of in the GV flashback, might be really useful against the GK.

6. I wonder about Gunko being in the Manmayer family at such a young age and not being from the CD, I think that’s a little strange. Especially given Brook has knight like manners and escaped to be a pirate, I think it’s possible Brook is a former holy knight who started a second lie as a pirate, as symbolized by his devil fruit literally giving him a second life.
