Hahahaha obviously, naruto wudn't suit having rinnegan but naruto will get it finally. By defeating obito he will surpass his powers to naruto entrusting his past dreams... And thats all how he get all that. Sasuke not at all, sucked up...
What? First, you contradicted yourself. Naruto won't get it but he will.
Second, defeating Obito does not equal obtaining his powers. If that was true, Naruto would already have the rinnegan since he already defeated Pain. Neither does entrusting his past dreams equal obtaining the Rinnegan.
Even if he defeated Obito and Obito gave him the Rinnegan, he would have one Rinnegan. that would look horrible on Naruto. Much worse than both eyes being the Rinnegan.
You didn't even try to logically explain why Sasuke won't get the Rinnegan.
When has Sasuke ever sucked up to anyone? This guy can't as much as use honorifics. He is arrogant and dismissive with everyone from Sakura to Orochimaru
It's out of Naruto's corpses to obtain power from corpses.
OP: neither will get the Rinnegan.
Naruto is the younger son, while Sasuke is the elder. So, Naruto will have the power of the body, but Sasuke will have the power of the eyes. In order to have the Rinnegan, you must have the body and eyes. However, neither do. Naruto is the body, and Sasuke the eyes. Neither will become the Sage. It would ruin their parallel. They will work together like the Sage intended to his two sons to do. Guess what? The Sage didn't see fit to give either of his sons the Rinnegan. Why would their parallels many years later need the Rinnegan.
