Everyone who complained about the fights being off panel in the last part of the arc really got an answer with these last couple of chapters: Don't worry you'll be seeing more action very soon.
I'm looking forward to how the match-ups are going to fall out.
Some guesses:
Trebol & Diamante vs. Sabo, Robin & Koala.
Barto playing shield for Usopp & a face-off with Cavendish.
Franky & (possibly) Bellamy vs. Dellinger, Senor Pink & Machvise.
Kyros vs. Lao G, Violet vs. Gladius (he's already called her out).
Kinemon vs. Kanjuro
Zoro vs. Fujitora
Law & Luffy vs. Pica & Dofla
Burgess owes nothing to anyone, he may even try to hunt down Usopp.
No idea if many of the gladiators will get more of a spotlight, but Kelly Funk has struck me as some sort of Chekov's gun since he first appeared. A guy who wears other people in an arc where the main villain controls people?
All sorts of wild cards running around here, which is great.
Huh? What is that sir? He is off to rescue him, not fight him
