I am pretty sure or at least a bit certain the Sasuke and Orochimaru will come in next chapter. Because this fight is getting to it's climax. Kishimoto won't want to ruin it for us that easily. I can't wait!
I hope so. Kishi really left us wondering who the hell people who know everything are. And they will probably tell Sasuke something that wii either make him even more crazy and hatefull, or change him. It's going to change the story...
i agree that he will switch to sasukes crew next chapter and if anything it probably show like 2 or 3 pages of the naruto fight then switch to sasuke fully.
I actually wouldnt mind if we saw some of sasuke/oro next chapter. Honestly anything but Obito flashbacks and i'll be happy. Those started really getting old.
