Well....as far as power, skill, etc. He is above Naruto....but you probably meant in the end Naruto will surpass him, correct? If so....I wholeheartedly agree.....
What I cannot wrap my head around is what exactly could Naruto or Sasuke receive to defeat him? Hashiramas binding Jutsu will no doubt play a part, but I don't think it will defeat him completely. Madara before becoming a Jin seemed faaaar too powerful for them to handle. His strength, speed, agility.....all of this has probably increased 50xs over....and before that he had no rival. I feel Kishi has a beautifully unique way of having him defeated. I believe he's been pondering it for some time nao..... I believe it will be nothing like Obitos...
How can they combat him, is what I can't understand.....I guess Kishi will surprise us! ^_^
