I hope next chapter is half roof top action and the other half should show us the final match ups under the roof
No final match ups, at this point, it feels like everybody is everybody's opponent and they can switch at any time. Look at King+Queen vs Marco, there is possibility of Pero taking over. We expected Samurais will fight jack, but inu stopped there, about Orochi, they slashed him and moved forward, now who will be the next opponent for Orochi and Jack (if he beats inu, which is highly likely).
Ussop+ Nami Vs page1 and ulti, there is intervention of Tama and her army,
Yamato Vs Sasaki, replaced with Franky, (matchup locked, but may be replaced again)
Jinbe Vs WhosWho (Jinbe may leave if he know that his captain is in a pinch)
Robin and Brook Vs Black Maria (Locked)
While it is important to focus more on floor battles, I think it is not the time to finalize the matchups. It is called unpredictability, and this is what that keep us keep on reading and awaiting for new chapters.
