Never ever thought of Tobi to be the brains behind Akatsuki... The whole time when he was Deidara's "sidekick" he must have been only watching. So cool that Uchiha Madara is still alive, I think we're going to hear a great background story.

Hmm, maybe I have to dig up the episode(s) where he was mentioned, only thing I remembered that he was the first to ever reach Mangekyou sharingan and did it by killing his best friend. But how long was that ago?

Naruto Shippuuden is really great nowadays, maybe the animators finally realized what they did to the story with their slow episodes and fillers.
