like last two manga chapters it explains only the need the essence of the tail beast chakra to bring about the 10 tail so even removing the 9 tails and implementing the 10 tails would make him the jubi host. so its still very possible
I dont see Sasuke getting Rinnegan. He just got EMS and he havent had the chance to use it... Kishi made Madara go Rinnegan / wood so that Sasuke would show us what EMS is all abaut. And Naruto will be > Sasuke for the rest of the searies. (joke xd)
