I'm sure the final arc will beat it. Far more characters and plotlines need to be addressed. I don't expect Elbaf to get to this length, but I can see it surpassing 100 chapters if it's more than just about Giants or Big Mom or the final Road Poneglyph. If he decides to adds anything related ro Vegapunk there, it's going to be way longer.
People thought Oda learned his lesson after DR, then he did an 80 chapter WCI arc with one major fight that was basically set up for Wano, a 140+ chapters arc. I do not believe he will learn anything about pacing lol
