I think he did, Kishi done this before with obito where it was obvious that it was him behind the mask but some/most chose to think otherwise, so with this I'm jumping on the kishi pattern train, where he is obviously dead but some people will say that he will come back somehow
Mate, someone as important as Obito wouldn't die off so easily...
He got his original left eye back for a reason, not to count that he wouldn't let Madara take him after what's he doe to Rin.
It might turn into one of those scenarios where Guy gets trapped in a dream or something, everything's perfect; Obito and Rin or something than guy realizes it's all fake and he wakes up to kill Madara. The end.
I don't believe that Obito is dead. Not too long ago BZ was bragging about the fact that Obito is only alive becasue he was attached to him and that Obito would die as soon as he separated from him. They are still together. I think he means Obito's will is dead.
I think Obito is letting him think that until he can come up with a way to help team 7. After that bomb Madara dropped on him about being played with over Rinn's death, I don't see him just giving up. He's waiting for BZ to show a weakness he can exploit.
