I saw a thread with this topic on BattleGround so I thought I'd put one here as well. Not predictions really just what you want to happen but I think the title is self explanatory. If this falls under the same category as the what you want to happen in One Piece thread I'm sorry, I just think that it would be nice to have something contained to this arc and its characters.
