I was windering whether SO6P will appear in the manga oro not and something came to my mind....we remember how minato appeared in naruto's mindscape when he went to 8 tails and tightened the seal....similarly a part of the sage's chakra will generate once the juubi reaches it's COMPLETE ORIGINAL FORM and he wiwll reappear only to divide the juubi's chakra into the 9 bijuu and then entrust the final job of defeating madara and co to naruto and sasuke....it would also be a bit ironical since his two sons had opposite mentality while naruto and sasuke being their descendants will finally team up together to defeat madara.....what do yiu think?
