Sadly, I know how it will go: Orochi is still alive, and will either A. be defeated and captured by the Kozuki, but jailed instead of executed, because "they're better then that", or B, and even worse: Everyone realizes how the hate of his clan caused him to be a monster and he tries to redeem himself or some bullshit.
Personally, I hope he's dead, for real. Him dying only finally realizing he was just a pawn to Kaido all this time feels much more satisfying then whatever Oda had planned.
