great chapter, and some questions answerd,
1) madara never had a chanse yet to get the rinegan, konan has been guarding, hiding, protecting it, but for something madara realy wants to have it, perhaps to be able to read the full text on that tablet underneath the uchiha shrine
2) kisame died in the most honorable way a shinobi could die, protecting his comrads by not letting any information on them leak out, and completing his mission of gathering intel on the kage's and great countrys, and since there is no trace of his body I don't see him being brought back to life, perhaps only by edo tensin.
3) since only konan seems to know where nagato's body is it seems that for edo tensin to work you don't need to have the actual body or acces to it. since kabuto summond nagato, but he also could not know where the actual body is.
and perhaps now we will see what konan and madara are realy made off, but I think we are only going to see the outcome of the fight
