In the Pain arc Nagato uses Rinne Tensei to revive all the Konoha victims. We see Konan thinking how doing the jutsu at his remaining chakra levels will kill him, implying that had he had more chakra he could have survived. Here's the page:
And this is what we find out in chapter 614. Obito says he will die if he tries to revive Madara.
Clear plothole. Konan implies Nagato would have survived and Obito says he would die. And don't start with the Nagato was an Uzumaki mumbo jumbo so he could have survived because Obito has Hashirama's cells.
Anyway, I made my point. Thanks for reading.
