Damn I thought you had a theory but you have got something even better. A living 4th sighting! Wow, dude is like elvis. Once again......The fourth is DEAD! If he was alive, why/how did Orochimaru almost summon him on that roof, that day. Its clear Oro was attempting to summon the other three hokages, now if one of them wasnt dead, then there wouldn't have been a third coffin.
Whats up with people saying the 4th is alive? They say he's the leader of Akatsuki, he's naruto, he's here, he's there. Dude is dead. All the people carved into the side of that mountain are dead. Desceased. I know he was cool, but he's dead.
