probably gonna show who he is in chapter 600. a lot of big things have always happened in the 100's chapters, such as chapter 100, 200, 300, 400, 500, and now 600. i dont see why he would break the mold and show it all in chapter 599. we are going to be trolled, trust me. or like someone said above, the last page of chapter 599 is going to show tobi's face, and the entire story and his actual name and shit will be in 600. cause hell, we might not even know who the **** tobi is even if we see his face, so im betting on that. last page of chapter 599 is tobis face, no name speech bubble or anything, then we are all like "WTF who the hell is that!*$@". then in 600 all will be revealed.
all i know is it better not be obito.
