Danzo had tons of uchiha sharingans , shusi ms eye (when shsusi was about 13) ,senju dna for a long while but never get to unlock rinnegan.Why?Even Obito had MS and senju dna from 13 to 30 (curently ) but never get rinnegan.Madara said he did not feel the effect of senju dna till later down his life span.I want to know if this a plot hole?
In addition ,this show inorder for a senju member to obtain rinnegan they must get rinnegan eyes from a uchiha ,they cannot obtain rinnegan naturally.The senju can obtain the uchiha clan strong spiritual energy and powerful chakra ,yin -yang release instead of the rinnegan power.
Theory
Sasuke will get the elder son version of the rinnegan because it the only eyes that belong to the uchiha ancestor .I believe kishimoto will not make sasuke get rinnegan by obtaining senju dna because madara and obito have part rinnegan.Probably hawk sage mode will give sasuke the chakra capacity to unlock the rinnegan instead of the senju dna.Sage mode allow the user to absorb nature chakra
