I think Naruto would die in an old age not when he will fight Sasuke since the battle will end like Hashirama vs Madara though Naruto always got close to Sasuke but it was hard for him to see Sasuke but Naruto won't kill Sasuke that's so predicted U_U I think Kishi will find something we can't think of.
:rofl:Naruto will be a head of sasuke
