I would just like to say...when the hell did Tsunade punch a hole through Perfect Susanoo? She never did that, she punched a whole through Madara's regular Susanoo, NOT Perfect Susanoo. Madara used Perfect Susanoo and then before either Madara, or the Kages, could do anything, Itachi released Edo Tensei and Madara's Perfect Susanoo disappeared since he was getting sent back to the pure world. All he did with Perfect Susanoo was chop some mountains in half, and Tsunade definitely 100% did not touch Perfect Susanoo. So I don't know why any of you are debating that since Tsunade punched a hole through Perfect Susanoo that Naruto couldn't with Bijuu Mode. It just didn't happen, and we don't know what is capable of punching a hole through Perfect Susanoo, but I am pretty sure Naruto could destroy a normal Susanoo with ease in Bijuu Mode, since Tsunade did with just a punch.
Also, I for one thinks the Sage had the Rinnegan BEFORE sealing the Juubi inside of himself, for one simple reason. The Juubi's eye is obviously not the Rinnegan, is is more of a Sharingan with more Tomoe's, and the Sage's Elder Son's eye is obviously not the Rinnegan. Isn't it safe to assume that if the Sage did not have any Dojutsu beforehand, and got it after the Juubi was sealed, that the Elder Son would have the Rinnegan and not some mutation? But if the Sage had the Rinnegan before sealing the Juubi, and then the Juubi's eye interfered with his Rinnegan, that the Elder Son would have a mutation of the two that would eventually lead to the Sharingan? I just think that since the Elder Son didn't have a Rinnegan, that the Sage must have had it beforehand and the Juubi's influence mutated his Elder Son's eye's into something that wasn't a copy of the Sage's Rinnegan.
