Man, nobody really though that Zoro would have fought Orochi as his main opponent in the arc.
The bet was essentially on Kaido in a tag team with Luffy or King.
Everyone know that Zoro is a powerhouse, Sanji's fan included.
On the other hand there were plenty of people convinced that Sanji would have fight Page One or another mid flying six or half dead Jack at most.
It was entertaining to see Oda first putting him against Queen (and then started the all "Sanji is gonna receive help by Drake, Apoo, Chopper" thing), then letting him fight a YC in base and now giving him a huge boost in power that put Sanji on an even higher level then before.
That's all.
