At this point I'm more convinced Act 3 doesn't end until all matchups are fully defined.
- will P1 and Ulti get up for Usopp and Nami?
- will Chopper join the fights? Will he help Usopp/Nami? Will he fight Numbers? Will he fight *gasp* Jack?
- Who will actually fight Jack if not Inu?
- Will Zoro recover and fight King (imo, obviously)?
- Is Yamato staying on the roof permanently? Win or Lose? Or will she be used to fend of potentially Jack?
Really these are the big ones. 4 Strawhats are currently unmatched. 1 additional one (Yamato) is placed but not fully confirmed the arc defining matchup, as we can clearly see with Killer and Zoro. 4 BPs and Numbers currently are either unmatched, defeated (temporarily), or do not have clearly defined matches yet.
All I'm hoping is 1018 or 1019 make this a bit more clear. Really it seems more like Page 1 or Zoro recovers first and they encounter Usopp and King respectively. Those seem to be the next events imo
