I'm still in the camp that this Kid and Law vs Big Mom fight will be interrupted, but that Kid will get to fight Kaido later on and deal some significant damage. That would be a great pay off to the "you'll pay for this Kaido" scene he had with Luffy at the end of act 1.
I guess next chapter will focus mainly on Momo, Yamato and Luffy, and I predict that we'll see Luffy getting the upper hand like Law and Kid did in this chapter.
And it seems that something is being set up with Ussop, since he's being separated from the rest of the strawhats. Could this be set up for an Ussop fight or something else? Maybe the theory that he'll be captured and tortured like he's been saying foe chapters will become true.
Also I've noticed that everyone has been performing well in these recent fights, we saw what Kid and Law did this chapter, Luffy is out there splitting the sky in his fight with Kaido, Sanji is out there doing grill shots on Queen and shattering his sword. The one exception is Zoro, he has mainly been thrown around by King and hasn't been able to put up a fight.
I think Zoro might be out of the monster trio at this point guys
