Well....we've got from the good guys....

Luffy, Zoro, Sanji, Usopp, Franky, Chopper, Nico Robin, and Brooke

From the bad guys....

Moria, Dr. Hogback, Perona, Absalom, Oz, Zombie Zoro, Zombie Sanji, Zombie Brooke

So right now there's 8 good guys and 8 bad guys.
Of course...it seems too obvious to pair the swordsmen with the zombie swordsmen, and of course Sanji's going to hunt down Absalom. I can't imagine anyone fighting either Moria or Oz except for Luffy, though...
