Rinnengan vs Kages
I think Kishi has been holding Madara and Obito back honestly. If the Kages go to the battle filed right now the way madara and Obito are fighting, Madara and Obtio are going to get trashed.
Im guessing Kishi hasnt made Madara or Obito use all the rinnengan techs to make them save it for the kages.
If Obito and Madara can use the rinnengan like Nagato then it will be a fight, but if they dont use it....yeah i cant see the fight going too long.
Like shinra tensei, asura, etc etc.
