Sasuke has been really original even amongst the other MS users. His MS looked way different from everyone elses and so does his EMS. His battle style has always been unique and cool to watch. I hope they keep him different like that rather than make him just another EMS/Rinnegan moves spammer like Madara. One of those is enough to stomach.
I agree with this statement completely. Sasuke ms was different from all other ms. Sasuke's ms colors were inverted. This can not just be a coincidence that out of all uchihas who unlocked the ms, sasuke ms is the same as theirs. Sasuke's eyes are most likely special and and what happened to naruto(in the case of him not actually turning into the ninetails but using it in a humonoid form) will probably happened to sasuke. If he gets the rinnegan maybe his will look different than the so6p.
It is possible that kishi will throw in that the rinnegan is incomplete and not at its full power since you have to switch from sharigan and rinnegan in order to use certain abilities. Knowing kishi he could throw in that in order to complete the rinnegan you have to fully combine your sharingan and your rinnegan in order to the true eye. If this would happen then it would show why sasuke's eyes are special. This way sasuke gets a unique eye that only he has and since naruto already has a unique form, their final battle will be one of the best if not the best fight of part 2.
