Agree with Kusanagi. That annoying paper woman is gonna interfere with Nagato's otherwsie swift demise. He can't do anything anymore. Last chapter, Naruto resisted his chakara. There's nothing left he could do

I agree that we're not sure how weak Tobi (Uchiha Madara) has gotten over time. But if Pain and him fought at their maximal capacities, I believe Madara would come out on top. When Naruto was born 16 years ago, this guy had already mastered to Sharingan to the max. He almost obliterated the village and it appears that his sharingan is still quite strong. He did survive a Amaterasu. "The black flame that consumes even fire it's self"
About Kakashi's Magenkyo Sharingan, it doesn't cut. It sends whatever the target is into another dimension. The proof behind this is how he was able to stop Deidera's (I know I spelt that wrong. The exploding clay guy) tremendous explosion.
