I do not get the idea that calamity fights need to be shoved at the backend of this volume (vol 101 is 1016-1025). Page 1s defeat isn't even in the volume. 3 more chapters doesn't constitute remotely enough time to take out Kaido's top 3 henchmen. I think a lot of people are expecting the same results as the F6, where 1-2 chapters suffice. Queen is the same monster that recovered almost immediately from Big Mom's 2 attacks.
There are also like 5 other villains aside from the Calamities and Yonko. Not sure why we expect them to go down after. Some were also featured this chapter too.
Well I think that maybe the Dukes will lose their fights, where Carrot will recover and defeat Perospero and Jack maybe defeated by a tag team of Usopp, Chopper and Brook. Since Marco is done it is clear that Luffy is defeating Kaido one on one becoming the world's strongest pirate after Wano. It will be interesting because Luffy is always the underdog but maybe against BB it will be the other way around where BB will have to catch up to Luffy
If Inu doesn't win, certainly a combination of that or maaaaaybe Yamato gets sent back down by Luffy. I can see Jack joining Queen and King, which could be an issue for Zoro/Sanji. Conveniently there is a giant hole in the ceiling which may allow Yamato to just up and join that fight, if Oda needs someone powerful enough to fight Jack. Alternatively, there are still 4 Numbers left. Maybe some of those aren't 1 shot material for Chopper/Usopp/Brook etc.
No idea what's happening next, just think we got a ways to go before we see calamities fall.
