this is just a THEORY but it makes o alot of sense...there are 3 people that can probably be the sage but remember this! you can be the rebirth of the sage by having both senju and uchiha powers within you(because the sage divided his powers in half) and obviously the rinnegan sooo my candidates are:
1-madara!!! why??? he already has both sharingan and rinnegan and he sed he had cells of hashirama inside him and we can clearly see he has some kind of hashirama clone or shit in the manga.
2-naruto!!! because he has senju blood and itachi gave him some of his powers meaning that he has something inside him thats pretty much uchiha...the rinnegan?? well i belive he will unlock it sooner or later by some co0l and unbelieveble way!!!
3-sasuke!!! why?!!! because he is uchiha and i believe that madara gave him the left rinnegan eye and somehow fused hashiramas blood with his uchiha blood!!!
this is my thought if you can make more sense to this or less sense feel free to comment!!! thanks for reading!!!
