Sasuke was able to defeat bee with amaterasu. We also know that sasuke can manipulate the flames of amaterasu. The EMS is bound to improve this ability to such an extent as to defeat naruto. All he needs to do is trap naruto in a 3 dimesnional barries with amaterasu. when naruto breaks through, hell just die.
he can also defend against naruto taijutsu with an amaterasu shield like he did against raikage
Since he is lightning nature and his sharingan has the ability to copy moves. He could have learnt how to use lightning to augment his reflexes like how raikage did so in his battle against sasuke. This will definately give him the ability to dodge the bijuu bomb.
I like both naruto and sasuke so i predict theyll fight each other till they both dead
