I am confused. If the juubi was originally a tree, and now has transformed once again in that form. Why does Obito still looks like juubi's jinchuriki?
Also even if all the chakra is gone after this. There are still bijuus. Kurama and eight tails. So I really don't see that the manga will end with no chakra. What I think will happen is the juubi will overpower Obito and go on rampage.
Also people don't forget that Naruto has all of the bijuus chakra in him self, plus natural energy. So he also has a tree in him self
