True that, however i lead the the assumtion that when he consumed all that chakra, he obtained "all that power". It's controversial in my opinion, there could be many translations because theres like 3 different japanese languages.
Yes, but Kishi uses only one as far as I know. Also seen the situation it would make no sense at all that Naruto, who just got a humongous chakra boost, would say he still has all that much power left while the Kyuubi is dehydrating by the second, but still is making that massive chakra blast.
I don't actually get as why people are so confused about that line of the Kyuubi. If you just think logical, there's nothing weird about it. I've not read all the posts so far, so most of it probably already has been said already, but I'm still going to say it:
- Naruto is likely a Senju. It has never been stated specifically, but there are countless of indications and above all it would make the most sense. It all started with Uchiha vs Senju since the death of the SO6P. That rivalry has been going on for centuries, via Madara vs Shodaime, till the current time. It would make no sense that Sasuke, who's an Uchiha and embodies all the aspects of this rivalry, would clash with someone who's not a Senju. As we know he's going to fight with Naruto sooner or later and seen all the indications Naruto should be a Senju. If not it makes absolutely no sense at all.
- Now as we take that Naruto is a Senju, we can move forward. The Senju's inherited the body of the SO6P, with other words they inherited the physical container for a Tailed Beast as the SO6P was the host of the Juubi. This leads to the fact that he also was the container of the Kyuubi as the Kyuubi is a part of the Juubi.
- You can see the body of the SO6P as a blueprint he gave to the Senju, just like he gave his eyes to the Uchiha. No matter the Uchiha, he will awaken his Sharingan at some point as he was given a blueprint of it by the SO6P and it's my idea it's the same for the Senju. However they got the blueprint of his body aka the blueprint of a host. Of course you can't awaken that, unless a certain condition is met: you come into contact with the chakra of a tailed beast.
- When Naruto got into touch with the Kyuubi frontal and absorbed his chakra, the blueprint reacted. Just like if you would throw a burning lucifer on gunpowder, which instantly explodes, the blueprint of the SO6P in Naruto reacted on the chakra of the Kyuubi (and thus the Juubi). This reaction was, outside looking for a sec like the SO6P, a sealing jutsu. Where did it come from? Naruto doesn't know sealing and that seal was even stronger than Minato's Death Reaper Seal. It's obvious not Naruto's, it's from the SO6P. Madara already said it: the host-system has barely changed since it first was used. Just like every Uchiha has a Sharingan in him, every Senju probably has the blueprint of that sealing jutsu in him and that's what the Fox was referring to: the sealing jutsu Naruto used.
- Of course there are degrees in it, not every Sharingan is as strong as another, same would go for this. Though in theory every Senju would be able to use it, just like every Uchiha could achieve MS. The result of this is that Senju's would be the perfect hosts. Only a handful of hosts was able to control their beast, most of the hosts died or lost control, but as far as we know none of them was a Senju. Naruto was probably the first Senju who became a host. It would make some sense as the 6OSP was the one who made the host-techinque, it would be logical that he not only made that technique but also passed down the tools to use it at its fullest.
Summary: The point I actually wanted to make was that Naruto is not the S06P, I don't get as why people think he is. If you even think for a second the S06P splitted himself into two to put it like that: Uchiha and Senju. So how is it possible that Naruto would be the SO6P if he's divided into two? Maybe if an Uchiha and Senju would breed with each other, but in this case what we saw was a reaction of the Kyuubi's chakra on Naruto's body, which contains the blueprint of the SO6P's body. This reaction could, in theory, happen with every Senju who comes into contact with any tailed beast.
This is just a theory and depending on the next chapter it could be broken or made.
