Orochimaru said "them" so it's multiple people that both Oro and Sasuke know, which means it's either the village Elders or Sasuke's parents. (Oro knows them because he researched Sasuke.)
I really hope so. However, it would not surprise me in the slightest if Kishi didn't even show Sasuke next chapter or if he leaves us with us some other cliffhanger before revealing who the person is -__-
Season 2 of the anime has been green-lit, but there is no official release date as of yet. There have been speculations that it will be this spring, since the manga is far ahead of the anime, which leaves a maximum of around 3-4 months until season 2 starts if the speculations are correct.
I dont even get my hopes up anymore and I havnt for a long time the story is moving at a snails pace. I just prepare my self for Bleach now and just watch Naruto to stay on track.
I think so but there is no way to say for sure. All i can say is i think it will be revealed within the next 1-3 chapters. If it isn't Kishimoto being a douche lol
