Anyway I feel like this arc is a redemption arc for Lucci and Kaku.
These arc the hints so far:
-Lucci questioned the World gouvernement desire to kill Vegapunk and mentioned Lulusia.
-Lucci and Kaku now know the taste of treason and should understand Iceberg's feeling now.
-They tasted defeat again at the hand of the strawhat.
-Robin seem to have moved on with the past as shown with her stopping Nami from kicking Lucci.
-They failled the WG and worst have gone against order and will be punushed and killed.
-Now they are powerless and at the Mercy of their enemy.
This scenario kinda remind me of Hachi in Sabaody.
Kaku and Lucci are the Hachi of the arc.
I feel like Oda is building it slowly but the goal is making Lucci ans Kaku Ally or at least a futur oponenent to the WG.

I wonder what is gonna be zoro next plot he got lucky to be with oda's "son" probably something related with lucci kaku or saving the others if they fall into a trap?
I think its all these stuff you mentioned above.
-plot with Kaku and Lucci. Oda didnt left them in front of them for nothing, something will happen.
-plot with Kizaru and Saturne they gonna fight.
-They gonna get Epic introdution when the strawhat are in danger aking of Rayleigh.
