So, N'Zoth's presence still being active can make sense. And if 10.0 is the Light and Shadow expansion with the Dragon Isles, Lothraxion and Yrel, Sargeras, the Void Lords, etc. Then that would be a perfect expansion to continue the N'Zoth ordeal.
Mind you that Alleria also heard new voices outside of the existing ones when N'Zoth died. Maybe the Void Lords + the Other Old Gods are laughing at her from the Void?
