Forum:Which Yonko?

So after that last chapter the big question is...which Yonko is Caesar talking about? I feel it's safe to say for the sake of less argument that it isn't shanks, just because:p Blackbeard seems unlikely as well because we know from Jinbe that blackbeard's crew are hunting for the strongest devil fruits so for them to be buying loads of artificial zoan seems unlikely? Which leaves big mom and kaido, Big mom seems likely as pekoms and tomago are seen to be in contact with caesar and an army of zoans to me could be what tomago was talking about when he said 'the monsters of big moms pirate crew' However it could also just as easily be Kaido as we know nothing about him, personally I would love it if it was because then Luffy would have pretty much declared war on two of the fourXD What do other people think?
