yoo i had da craziest thought reading this thread about uzumaki being related to the uchiha ok idk why i never realized this but hashiramas wife was an uzumaki thanks to her madara could no longer control the 9 tails my theory is that if sasuke and naruto fight naruto is not a senju so the whole curse of hatred between them doesnt have to continue sasuke is not going to fight a senju but an uzumaki so this would be different from madara and hashirama because that fight was uchiha vs senju now its uchiha vs uzumaki so the whole sasuke has to die thing isn't confirmed yet i think naruto being an uzumaki will be the deciding factor to the battle instead of being chosen by fate as tobi stated i think they will decide to end the fighting and make their own fate think about it (naruto as hokage and sasuke leading the anbu black ops it would be a perfect ending ) as a side note it seems that uzumakis have a connection to the kyubbi as kushina mito and naruto were all jinchurikis for kurama its all a strange turn of events i have another theory on why narutos chakara cloak isnt red like other jinchuriki as well but ill save that for next time
