It would kinda suck if he does, madara fought to the death and right before "dieing" discovered that power. Sasuke just got EMS and we haven't even seen him use it and he already going to get rinnegan? Doesn't make sense to me.
After he shows us his EMS abilities, he can get the rinnegan then. I am too excited for EMS for now. But, most certainly yes; my favourite character will get the rinnegan.
Sasuke isnt ganna get rinnegan guys deal with it he need senju dna like madara to activated rinnegan (that's what i believe)
hes op already with the EMS big susaano with black flames (amaterasu) lol what more do he need to beat naruto he maybe have more up his slave
