@Kishido:
Well I doubt that but again about Zoro…
He is loyal as fuck and putting his pride away to become stronger for Luffy was one of the best character developments for him ever. And of course Thriller Bark
BUT Zoro said more than once if Luffy ever will stay inbetween his goal he will go... Or like in EL where he said...

In Fishmen Island he said (even if I not seriously)…

Again… I do not take it seriously... But in Punk Hazard he yelled at Luffy again for not being "serious"
And now again... + the panel where Inamushi is talking to all and Zoro simply walks away.. It was even highlighted but not like a joke where he goes to sleep or something
Which makes me wonder if that theory that every SH's going to leave the crew and re-join will turn out to be true. After Usopp, Robin, and Luffy himself (the 2y3d was kinda selfish, how Nami put it), now we have Sanji leaving, and enough evidence to think Zoro will leave too once he gets his chance to fight off the strongest swordman.
@Katzztar:
Its likely Jack. Remember that Wanda said the newspapers covered his supposed 'death' while attacking that Marine convoy. So we do know that Jack was in the papers
Oh, yeah. I had forgotten about that. Poor, ruthless Jack. He (didn't) died so fast.
@King:
Usopp kind of did this back at Water 7.
True. But I was thinking some major betrayal, a la Squad with Whitebeard (though I know Squad wasn't a member of WB's crew).
@jazzflower92:
Big Mom vs Kaido, that would be an awesome conflict to see.
BM vs Kaido, while the Marines and the Supernovas fight against each other in an attempt to clean up the Yonko's remainings.
