After the release of the new chapter, these are my guesses:
Franky and Robin will save Usopp and Chopper, who will tell them both that Nami has been kidnapped. Franky will take on Absalom and Robin will take on Perona, while Oz falls asleep. They will fight equally with no clear winner for a few panels, somehow rescue Nami from Absalom and flee before a winner is decided. Moria will send Absalom and Perona after them.
Franky, Robin, Usopp and Chopper will get to Sunny, where Luffy, Sanji and Zoro are. They will wake them up and then Absalom and Perona will arrive. Robin will fight Perona and Sanji will fight Absalom. Luffy and Zoro will go find Moria, and team useless plus Franky will run off to try and retrieve the moster trio's shadows.
As one would expect, Zoro and Luffy will lose their way and get seperated. Zoro will wander around, finally coming across a defeated Brook lying on the ground. Brook will say that he cannot defeat Ryuma alone and that he needs Zoro's help. Brook'll give him some salt, and Zoro promises Brook he will defeat Ryuma.
He walks through a doorway and spots Ryuma whistling to himself, drinking his tea. Ryuma will tell Zoro that he doesn't stand a chance and that he is the legendary swordsman who slayed a dragon and whatnot. A fight will then begin.
Luffy'll finally reach the room where Moria and Hogback are, seeing a defeated Oz and a wounded Moria. Luffy'll summon Moria to a battle, saying he'll kick his ass, so Brook can join his crew. Moria'll say that Oz tried to rebel and defeat Moria, but Moria defeated him, and if he can defeat Oz he can defeat Luffy too.
Moria and Luffy will then battle, and although Luffy has the advantage because Moria is wounded, he will be defeated. Moria and Hogback will then leave.
Whenever and wherever, team useless and Franky meet up with Hogback and Lola. Nami will defeat Lola fairly easily, and Chopper will OHKO Hogback with the Roseo attack or whatever it was (I doubt Hogback is a fighter, plus Cindry wouldn't mind). Team useless and Franky will purify some zombies, fight some generals on the way (Usopp VS. four handed sniper hint hint), and get back Zoro and Sanji's shadows.
They'll find Luffy all wounded, Chopper'll take care of his wounds and Franky will purify the defeated Oz. Luffy will go out and search for Moria, find him and eventually defeat him with a gear third rifle or some other shit.
Zoro, Sanji and Robin will defeat Ryuma, Absalom and Perona respectively. Zoro will purify Ryuma with the salt Brook gave him and Robin will OHKO Bearsy with a clutch and purify him.
The end! Fwee!!
Basically I'm saying final fights are:
Luffy VS. Moria
Zoro VS. Ryuma
Sanji VS. Absalom
Franky VS. random zombie generals
Robin VS. Perona
Usopp VS. random zombie generals
Chopper VS. Hogback and random zombie generals
Nami VS. Lola and random zombie generals
I'm pretty sure more than half of this will turn out wrong, but it was fun guessing.
