What I think will happen is some lame attempt to seal her away. Black Zetsu retreated to Kaguya and she might be about to attack. He seems to be the only one capable of explaining further how things happened. And so it will be a chapter in preparation for that sealing jutsu. I don't think Madara will return soon maybe from here to 7 more chapters but when he does he is going to do some crazy sh*t! It would be nice if Hamura appeared in some form and told Sauke and Naruto his side of the story. What I want from the manga is background on Kaguya and Hamura after that is cleared out. Kishi can do whatever he wants and it'll be fine by me.
From the above posts. Yeah, the hokages are free and unaffected by the infinite Tsukoyomi. They might be rescuing people from the tree as the battle against Kaguya goes on.
