I think i know how Sasuke vs Naruto will happen...

[Omega Pheonix]

Sasuke's Rinnegan contains tomoes , which seem to return after a while once he used his Shifting ability . Now take that into consideration and this aswell . Sasuke wants to Change the Shinobi system . Now I suspect that the Infinite Tsukuyomi will give him an opportunity .

He might Hijack the whole operation or wait for Madara to be defeated then cast his 9 tomoed Rinnegan/Shiringan on the Moon . Which will prompt Naruto to argue with Sasuke , resulting in a fight that determines who's will is stronger , Sasuke's or Naruto's .

Naruto will fight to free the people from the Tsukuyomi , while Sasuke will fight to change the system ...

Any thoughts ?

sasuke is not evil never was. no

That would be a plot twist and one I wouldn't mind.
