Yeah if he going continue to only show the battle at the rooftop, for sure the fight gonna end soon since Oda really want to end the fight quickly. The other battle didn´t yet full start, Oda going to show the fight above and end it soon.
The question is for me more what gonna happen after the lose of the Sn against Kaido and Big mom, something must happen so they could either fight back(if the raid successful in act3 without a break) or escape(fight starting again in act4, with means Oda should switch soon again around the one piece world with more juicy informations).
If the raid successful right now, i think the other Strawhats and also other parts taking their W, if not they gonna get defeated too soon. Let see which route Oda now choose, since their are more then just one kabuki threat versions where the act end overall in act3 without a big tragedy.
