I hope next gen Marines ( Coby , Smoker , Helmeppo , Tashigi ) will come but last time we saw them , they were busy escorting 50 Kings & Queens back to their kingdoms , the result of incident with Vivi/Cobra , and dealing with Mihawk , Hancock , Weevil , Buggy
At this point i have no idea how the alliance is not getting clapped in this "war". It should be called a one sided beat down.
At the same time i couldn't endure another phase of preparations for battle. Also, how is Oda gonna explain that the alliance loses but all the major characters get out alive and live for a second try?
It would make the Yonkou look even more incompetent.

What people seem to be missing about this issue is the very concept of the Kagura festival: its real world inspiration is an event of victory against the evil, commonly Yamata-no-orochi, so it feels like the perfect moment for the bad guys in Onigashima to go down. I think that the good guys will achieve, minimum, a partial victory and wouldn't suprise me if Orochi was defeated here at least.
Reasons being:
1. He's a slimy bastard that always somehow manages to wiggle himself outta of life threatening situations lolz
2. The order in which Oda had Luffy state he'd be defeating the current arc antagonist i s a bit odd, it was Kaidou, Lilin and then Orochi. Mind you, the Kaidou -> Lilin sequence is consistent with what Luffy said on WCI.
Maybe Neko and other people might come to Wano to help out as well
