Yes.. they will,
Sasuke has itachi's eyes now, to destroy and kill Naruto.. i dont know why sasuke has itach's eyes.. but Naruto now has complete control over the kyubi in manga 499. But, naruto said that both sasuke and naruto are going to die if they fight..
episode 212 or 213
They first fought on top of the hospital
Sasuke won the 1st fight and would not go to konoha
Sasuke fights Deidara on episode 122
no one knows. Naruto said himself that he thinks that the both of them will fight and die. But I don't think so.
there hasn't been a proper fight between them, even in the manga they haven't fought yet
naruto
naruto and saskue
Yes
I think saskue will turn good at the end of naruto series
saskue is killed by naruto because he attackes the village he has the upper hand in battle until naruto uses his sharigon given to him by itachi and kills saskue but some how the sharingon saves him.
No, he does not.
