Predictions:
1. Inu dies and Neko avenges him

2. I think we are gonna see a tag team with Zoro & Sanji v King & Queen and the later are gonna get destroyed
3. We will see the SHs flex on Kaido (i.e. Oars 2.0) pending the time Luffy gets back
4. If Oda is going to re-enact the Ryuma cutting a dragon scene with Zoro by all means then, a feasible scenario could be the SHs wrecking Kaidou and then in that sequence of attacks Zoro lands the final attack on him that drops him off Onigashima down to the flower capital where the final showdown btw Kaido and Luffy will happen (i.e Zoro killing Kaido is very unrealistic for a variety of reasons that I'm not gonna get into in this thread

but something like this I think will be good enough as an homage to Ryuma)
5. Law & Kidd will defeat Linlin with a combined attack
6. Next time we see Killer and Hawkins, Killer would've been through it

but I think he will win with a PU or sumin
7. Kin will survive thanks to Hiyori's abilities but it'd be too late for Ashura and Kiku and I suspect Inu will be joining them7
8. One of the Kurozumi will survive and my guess is that it'd be Kanjuro
9. Robin will be captured by Cp0 temporarily but Drake will lend a hand and intervene
10. Marco's purpose this arc is to die saving Luffy (I reckon he'd die at the hands of Blackbeard)
11. Sulong Carrot will defeat Perorin with a technique paying homage to Pedro
12. Momo will stop Onigahsima from falling
This is all I got atm
