Not normally a fan of this style of prediction, but not only does this seem plausible, for the most part, but also would be a very exciting chapter.
The one thing that I feel is a bit of a stretch is that Madara would be able to Kamui (I'm convinced Tobi's transportation is identical to Kamui, just better controlled) to teleport to any Sharingan. In the past Tobi's transportation seemed to be tied to Zetsu; i.e. he can teleport anywhere that white Zetsu or a clone of white Zetsu is.
