"Edo Madara > Edo Hashi > KM Naruto > EMS Sasuke > Oro > Edo Kages"
Depends on EMS Sasuke. I'd say soon enough we'll have confirmation on it. And so long as you don't count Edo tensei as Orochimaru's soldiers.. Also...When Orochimaru said he couldn't take Sasuke right now...He was speaking without him arm souls back.
It also depends on Naruto. I'm fairly certain the Naruto >> Kyuubi we see here and could easily kick the crap out of the Kyuubi by itself....as Naruto has dat speed, the Kyuubi's chakra, Shadow clones/multiple Kyuubis...and if all else fails...kick it's *** with Sage mode again. Naruto is not limited like the Kyuubi. He's WAY more versatile when it comes to utilizing the chakra of the Kyuubi.
Also...we have to wait a bit...People still argue that Minato can take Sasuke and Itachi(with good arguments). When Susano...whether big(like Madara) or small(like Sasuke atm)...would have the same effect against him.
