Kaido vs Big Mom

Does anyone else think that Big Mom might end up actually fighting Kaido in Onigashima? We’ve already seen her lose control multiple times. Maybe Kaido is forced to fight her because she goes berserk again?Also I just doubt the ability of the invading Straw Hats and co to handle even one Yonko let alone two.

Another possibility I can see is Big Mom betraying the Beast Pirates. Once again, a theme we’ve seen already with her. Maybe she understands that the Beast Pirates would not be expecting an attack, also they’re most likely incredibly wasted at the party. Besides, how trustworthy can a pirate alliance be?

At the end of the day, I think that both Yonkos will fall in this arc but maybe not how we originally think.
