The last and most powerful Jinchuuriki is and ofcourse will be Naruto. Now as for this one I don't really care and senseless kinda does describe how Kishi does things now doesn't it. I mean why was the capture of the two and four tails done off screen and why why did we not see any of the other jinchuuriki's at all. Anyway I'm convinced that the only reason we are even seeing any of this is because of Kishi's obsession with Sasuke, if it was someone else going after the eight-tails I doubt we would be seeing anything at all.

Anyway yeah he is probably going to be really strong but that still isn't going to stop him from getting owned by Sasuke and yeah since there are only two Jinchuuriki left you could call him the strongest all you want but he is still gonna get beaten by Hawk.
