why not they both get the rinnegan,tobi said nagato was the 3rd SO6P,that means after SO6P and madara,tobi 4th,sasuke 5TH,and finally after sasuke dies,naruto 6TH
he said he is the 3rd PATH, not 3rd SO6P; but whatever
now listen, i SERIOUSLY don't like Sasuke, ask anyone who knows me, i really don't. i like Naruto, yeah i do. but Naruto must not get Rinnegan, the most important reason is, that Naruto is the person against geniuses, he is the genius of hard work, sort of like Lee and Obito. AND as most people say, he represent's Sage's BODY, not EYES. it was always like this, Genius Of Hard Work vs Genius Of Eyes, some examples are:
1) Naruto vs Sasuke
2) Naruto vs Neji
3) Rock Lee vs Sasuke
4) Rock Lee vs Neji
so if Naruto gets Rinnegan, than it will be the BIGGEST troll Kishi has ever made. it will be totally stupid. i would rather see Sasuke get Rinnegan, but still would find it quite meh as Madara had EMS for QUITE a long time and he awakened Rinnegan closely BEFORE HE DIED, so i would find it meh if Sasuke after 2 days of having EMS would get Rinnegan would be meh as i said
