And how can it possibly be official ? There are two ways for it to be official; 1- kishi says it, 2-that chapter is published. The latest official chapter is 511, so it can at most be "rumour". Tobi is Madara, unless kishi says otherwise.
Those aside, that is a nicely drawn picture. Except for the fact that he has glasses under a mask, and tobi isn't even using that mask anymore
