It's possible... still, I prepear the 9 biju... If the Jubi was to be reanimed, it would mean that all the other Biju would be fused together... U_Ui think with chapter 572 kishi was trying to hint at it. Ive heard people say it will be tobi and naruto will fight solely with sage mode. But i doubt that is the case. I think Naruto will somehow seal the juubi insode him when it all goes down.
