Reason I don't think the seal will fail and why it will

[MAN OF SIN]

Well I read a thread earlier that said someone in Japan said that the next chapter they defeat Kaguya

She has all nature KKG, a massive truth seeking ball, and perfect Juubi none of which she has used. Near do we know why she needs an army. Plus Sakura hurting her with ninjutsu would be a huge plot hole. Ending it now would be a pretty stupid move. And RAWs have not be released yet so how would that person know.
