Tobirama said that while Naruto was making a senjutsu tbb, he was basing it off of power since Naruto wasn't doing anything but preparing to attack so what else could it be referencing? Only comparison? I out right gave you links where The Sage said all of the Bijuus would one day become one, be lead down the right path and know what true power is and all of the Bijuus there agreed that the Sage was talking about Naruto.Tobirama said Naruto will be a better Hokage? so Naruto has been compared to Hashirama cause he dumb, and he doesn't even have the Rinnegan never will and isn't the Juubi jin. Only comparison I remember bout Naruto and Rikudo is bringing Peace.

.Sure looks like Bijuus 1-8 are all there. Even a mini 8 tails, Bee might absorb it or might not but the 1 tails or 8 tails wasn't in the convo where they talked about Naruto being the next Sage, so if Naruto do gain all of them then it will be soon and Kishi foreshadowed it with the pages I provided.
I see you can even debate about it any more cause I provided manga proof and all so no point of dragging it on when you only repeat what I already countered.
