Everyone make theories that did not happen and I think that is why we should, as a community, be more humble and open to contrary opinions.
For example, the following will be things that I thought would happen but did not:
-Orochi Kurozomi will be a strong swordsman that will fight with 8 swords and be very proefficient in CoA allowing Zoro to enhance his CoA during the fight
-Sanji will use the RS to save his nakamas as a last resort
-Orochi is well respected by Kaido and he sees him as his equal, authority wise
-Nekomamushi is the traitor
-Zoro will fight King and learn/show to cut fire in the fight (still might happen tho)
So I was wrong, shit happens. And guess what ? It does not matter. It happens to everyone, so be less haughty with others.
