So far i see it... we will get the final fights for the Tobiroppo. Now Blackmaria vs Brook and Robin, which will end in the chapter (1020). Then we get some build up chapter for Zoro vs King, while the main storyline will be Drake fighting, maybe right now helping Marco. At the end of the chapter he will be beaten (1021) and Zoro joining the fight against King.
1022 + 1023 - will be about Sanji vs Queen
1024 + 1025 - about Zoro vs King
1026 + 1027 - Kid + Law vs Big Mum (including flashback about Kid story stealing whatever etc.) until Law beaten
1028 + 1029 - Yamato and Kaido flashback, ending with appearing of Luffy in front of nearly beaten Yamato.
1030 - Start of the final fight of Luffy.
Fight will go a few chapters, always some parallel scenes with Kid vs BM.
1035 then final fight chapter, ending with Luffy and Kid winning their fight, kinda parallel.
1036-1040 Epipeth of Wano.
