Naruto will become Hokage, he has the power and his the way he fights as said it the last EP is with out giving up and testing him self and he does this as if it was nautral to him, and another quality that 3rd hokage point out that a hokage has to be willing to protect all his ninja as if they where all is his family and naruto has show this a few times already, He protected so many and fights for there honor as well as there lives seen in many eps. the driving goal for him to achive this will to be recozide and not fear for what in him, but the fact that he want that strength to help others. I bet Naruto is almost a mirror image of the 4th hokage and the 3rd hokage see this and so did the guy that taught him the to summon the frog.
