It's better to follow Patterns that Oda almost always used in Long Arcs against a Powerful Villain & it is as follows:
- Volume 98 --- From Chapter 985 to 994 --- Focus on Nine Scabbards & Volume Cover was Dedicated for them
- Focused on Scabbards Side of the Story & giving them their Time to Shine
- Volume 99 --- From Chapter 995 to 1004 --- Focus on Worst Generation & Volume Cover will be about them
- Focused on Worst Generation Side & how they are the ones to Fight Kaido
- Volume 100 --- From Chapter 1005 to 1014 --- Focus on Beasts Pirates & Enemy Side & Volume Cover will be about them
- Focuses on Highlighting Enemy Side & showing all their Match-Ups
- Volume 101 --- From Chapter 1015 to 1024 --- Focus on Straw Hats & Ally Side & Volume Cover will be about them
- Will Focus on Straw Hats & how they Defeat their Opponents & Shine
- Volume 102 --- From Chapter 1025 to 1034 --- Focus on Final Fight & Hero vs Villain & Volume Cover will be about them
- Will Focus on Final Fight between Kaido (+BM) & Whoever is left for Final Round (Luffy + Co.)
- Volume 103 --- From Chapter 1035 to 1044 --- Focus on Post-Raid & Conclusion of Arc with a Final Cover about Wano
- Will Focus on Concluding Story of Wano & Reveals + Build Up for what's Next
This is the Pattern that Oda mostly uses in such Arcs. And Volumes with such Covers & Focus will almost 100% Happen
However it's possible there will be an Extra Volume for perhaps another Flashback (BM & Kaido Past maybe) but it's least likely
Also there is a Pattern for Last Chapter of each Volume, is that it works as a Tease for the Content of Next Volume & like a Kickstart
And they are:
- Chapter 994 --- Return to Focus on Luffy & Zoro + Apoo gets Antidote + Yamato Action starts
- This Chapter clearly is a Tease for Next Volume that will Focus on Worst Generation & Yamato/Ace
- Chapter 1004 --- Return to Focus on Inside of Castle & the Fight against Beasts Pirates
- This Chapter clearly is a Tease for Next Volume that will Focus on Enemy Side & who needs to be Taken Down soon
Now for Unreleased Chapters:
- Chapter 1014 --- Should be a Chapter that Focuses on SHs & a Tease that they will reach their Fights Conclusion in Next Volume
- Chapter 1024 --- Should be End of Inside Castle & Pure Focus on Roof where we will get to see Start of Final Round
- Chapter 1034 --- Should be Conclusion of Raid & Tease of how will Wano be from Now on
- Chapter 1044 --- Should be completely Outside Wano
So yes, according to Oda's Pattern, Chapter 1024 should indeed be a Return to Roof Battle & Tease that Next Vol. will be Final Round.
However i believe that Kid was shown Lost in Chapter 824 & Kid + Luffy Lost in Chapter 924 then imo we should see Most Supernova Lost in Chapter 1024 & Kaido will have his "Won" Moment just like Doffy was Standing after Luffy ran out of Gear 4 & how Crocodile was Standing when Luffy fell due to Poison in 3rd Round & how Enel was Destroying Sky Island after Luffy Fell from the Ship ... etc
