I'm predicting the next 2 chapters are focused on finishing Sanji vs Queen, and will also wrap up hopefully Raizo's fight in them as well. Then maybe 2 more chapters for Zoro vs King and wrapping up the rest of the background fights, except for Killer and Hawkins, cuz I expect that fight to be wrapped up when the focus is on Big Mom vs Law and Kidd. I can see that lasting another 2 chapters. Anything else need to be wrapped up before we go back to Luffy vs Kaido? If not then we might be starting the final fight in about 6 chapters. To be safe I'd guess 6-10 chapters, since Oda might spend 1 or 2 on Raizo, yall know how he is sometimes lmao
