My guess is that all the hyping up for Kintoki is to create doubt about this bout's conclusion.
The problem is that we still have way too many loose plot points that need tying down.
My bet is that either winning or losing, Odin will unleash the "end of everythin" and the story will end with the surviving Gods teaming up with the surviving human warriors to fight the Primordial Gods.
Or Siegfried will fight a fusion of the Primordial Gods or something.
...
Anyway, the saddest part is that there's probably not going to be a Rasputin vs Anubis.
The God of Death against the guy no one could kill would go so fucking hard.
