ZKK aside, I'm interested in how Oda will develop the nidai kitetsu plot.
It's out of character for Zoro to exchange his Blades for another when they are still available especially after the flashback he had in the King fight showing how much he cared about them, so one could think that he shouldn't replace one of his Blades for the nidai kitetsu, but on the other hand, Oda introduced it for a reason, with Zoro also showing interest in it
There is also the black blade plot, but I guess Oda might simply reserve it for later.
Furthermore, since there is apparently only a single Wano chapter left, it might be his last chance to visit Ryuma's grave and with the hype around Ryukugyu's reveal, it might take a good part of the chapter
