I think by the end of Wano and Luffy beats Kaido, we might be close to whatever endgame this is heading to.
Luffy would have bested both Kaido and Big Mom by now. So all that is left of the Yonkos is Blackbeard and....Shanks.
To say that Luffy bested Big Mom is like saying that he toppled the Marines at Enies Lobby. While the Straw Hats performed far better than anyone ever expected of them, they only 'beat' their opponents in the sense that they accomplished their objective (getting Robin and Sanji back, respectively) and escaped with their lives in the face of a foe that everyone expected to utterly crush them. Indeed, the final act of both arcs involves them running away from the overwhelming might of the respective antagonistic forces. It's less that they beat these opponents than it is that "they stood up to them and lived to tell the tale".
