Observation: Sasuke power up will affect the look of his susano one way or the other,sasuke having rinnengan is a possibility, but if I know kishi well,he like putting hints in some of the coloured manga pages if am right,in one of the last 4 mangas naruto had sage mode but has the cloak of the so6p ,his bijju mode alone still shows us that 9 tome on his cloak and on his neck.the possibility of naruto getting the power of the so6p brothers is not far fetched cuz we don't know if he had an eye power but we know the two brothers both defeated the T.Tbijju
What do u think.
