I think this chapter was kind of a tribute to kishimoto's father dying as well, it was really portrayed in this chapter and you kind of feel that sentimentality, thats the reason why they were showing minato and kushina and the titled kind of speaks for it self.
As far as madara, something crazy has to happen, im almost a little worried, that rumor bout kishi stating that he did not know how to take down madara might of been true. But seriously bro, if your having issues bout taking down madara, why make him even stronger??
Anyways at this point, their is no way i can predict this. My theory might possibly be teten might save the day, use the tools that madara spit out to save naruto, Yeah that would be the day. TETEN SAVES THE SHINOBI WORLD!
I mean at this point, wtf is going to happen. The answer may lie to the mysterious figure approaching sasuke and for those who have said its kabuto, its quite obvious that is not who it is. The fact that Karen mention this is some kind of ominous dark chakra and orichimaru even declared that he has no idea who it might be. That is definitely not kabuto, they would know kabuto a mile a way.
