I think it more then that. We forgot he learn his father move from feeling his charka in his body. What if the other Masters and Bijuu pass on their ability to him and each of them have a different element. Would he not have gain all the most insane ability ever beside the So6p. Then again if the Tail beast are right then so6p said how Naruto be even greater then him by giving the Bijuu something so6p cannot do?
1.) You barely made any sense.
2.) What power did Naruto get by feeling up his dad's chakra...? And why was Naruto even feeling up his dad anyways?
3.) Sage did not say the future Jinchuriki for them would be more powerful, he said that the future Jinchuriki will lead them down the right path. The Sage had the Juubi in him. For all we know, what he could have meant there is that they won't be 1 as in the Juubi anymore, but instead, 1 as a family, unity, etc. And through their power of team work, they can prove that the 9 of them are far more powerful with team work instead of 1 power hungry, evil 10 tailed beast form.
4.) Back to feeling up his dad, yuck. But if you say the words "he learned how to use Flying Thunder God technique from his father, Holy ----, I'm going to flip 1000 babies over. He DID NOT LEARN THAT TECHNIQUE. He doesn't even know what the hell that technique is, probably not even it's existence. What we saw back on the Turtle Island was PURE SPEED. He crashed into the wall FFS. If he teleported using FTG, he would be standing on the wall or next to it, not smashing into it and spraining his ankle.
Back on topic. Naruto is very OP right now, but not OP enough. He has to fight against 1, 2 possibly even 3 Rinnegan users. Tobi, Madara and possibly Sasuke. Knowing how Kishi just LOOOOVES to give these Sharingan users constant upgrades in eyes, I doubt Sasuke will NOT get the Rinnegan. There's no way EMS can go up against Naruto right now, he needs the Rinnegan to fight Naruto. So that's probably why Naruto is getting all 9 beasts on his side. 1 final fight to rid the world of the Rinnegan and Sharingan.
