This chapter cleared a lot of theories and ideas... Almost like kishi is reading our posts and decides to give answers to our questions.
1st of all -> naruto won't work with the fox any time soon... He seems concentrated in the rasengan biju ball thing. And we won't see him fight untill the very end of the battle.
2nd -> no previous hokages for anyone. no jiraya also. Good!
3rd -> edo tensei is a mean technique... basically a summon (meaning that you only need chakra for the summoning itself and not to maintain it) that what it summons is basically invincible... And it seems it doesn't bring any drawbacks to the user... All is explained... But kabuto didn't say how to break the technique...interesting...
4th -> madara is afraid of kabuto... that's what i get from this chapter...
5th -> kabuto has more up his sleeve... what can it be?
6th -> now we know that the 6th coffin can't be the SO6P, or shishui or jyraia... Because kabuto didn't have acess to their DNA.
7th -> what is the whole "weapons of the six paths of pain" that may have the SO6P DNA?
8th -> why the hell does everyone talk about shishui but we still don't know a lot about him?
That's my thoughts about this chapter... can't wait for the next one...
