I think we'll find out who tobi is next chapter. I don't know what the bulk of the chapter is going to be about. I have a feeling we might have a change of scenery because they have been focusing on the Tobi fight for a while now.
I have a feeling next chapter is going to be one of the chapters that shows 2 or 3 of the main things happening right now. (tobi fight, sasuke's group, madara and kages)
