Re: 487 Predictions/Spoilers
maybe in long term but we get some leads about sasuke becoming the new pain he like naruto training hard with more physically related help (ie narutos mass shadow clones and kyuubi energy) and a few intense days of training gets it down. then naruto becomes sasuke in that he trains through using others ninjutsus and maybe using the kyuubi and unleashes some super known or super obvious hack kinda accidently in heat of battle. then they both go at it in a naruto v pain rematch.
maybe kb trains with naruto in jinchurri control a/o gaara with his time spent with his.
