Dats not a fact he suppressed da fox chakra not da fox while da fox was sealed away in naruto in da first place ...I think I was da first to state dat I thought sas could still do it and until it is proved wrong I will keep it in mind it was done before it can be done again but my vote is sas he won da first fight...also look at sas eyes day differ from all other ms (in color) witch leads me to believe dat he would be able to do some things not achievable by any other ms or ems userthats true im not gonna underestimate sasuke who can suppress the kyuubi but he can't now because naruto does not need to interact with the kyuubi so obtain its power because he separated the chakra from the nine-tails and and imprisoned the kyuubi within another seal. So no suppressing the kyuubi for sasuke lol
Why do you think the show is called NARUTO. Propebly because he is THE CHILD OF THE PROPHECY. He will bring peace to the world, and he has to beat the evil to do so.sasuke would win........like he said to naruto in the beging. "you should have spent your time traing instead of looking for me." also madara would have tought him som pretty crazy things with EMS... all naruto has is killer bee,and sasuke almost killed him without EMS.
Sasuke just implanted Itachi's eyes so we don't know what is his new power yet. Also like what Madara said dont underestimate an Uchiha.who will win?
