Sasuke now has senjutsu chakra, he now has the recipes for making Rinnegan stew, the only thing remaining is a "near death experience", which Madara just handed to him on a platter of gold.
Opinions pls, hasn't sasuke's chances of obtaining the Rinnegan just sky rocketed to a 110%?
We don't know what the requirements for rinnegan are. All the facts we know are:
1) Madara got rinnegan
2) Madara had an unusually powerful set of EMS
3) Madara had Hashirama's cells physically implanted in his body
4) Madara needed to wait many years (decades) to unlock the rinnegan, until he was an old man
5) Madara read the Uchiha tablet, and likely knew some secrets about the eyes that Sasuke doesn't know.
These are all facts from the manga, but we don't know which ones are required for Rinnegan. Can sasuke unlock them without being an old man first? Does he need Hashirama's chakra, or does he need Hashirama's physical cells embedded in his body? For that matter, does it need to be Hashirama, or can it be cells from any Senju? Is there some secret on the Uchiha tablet that he needs to read first, or does it just happen? Was there something special about Madara's eyes that make Rinnegan possible, or can any Sharingan do it? We don't know, so we can't make any assumptions about whether Sasuke will get rinnegan or not.
