hmm, Tobi = Obito theory with all the "proofs" still seems like complete and utter BS.

That would be, er... interesting, but it is SO farfetched that it's not even funny :P

it's so obvious that Tobi is from Sarutobi's family like boilerph said.

I mean - they both have "TOBI" in their names !!!!!!!!!!!!! lol

Maybe it's Sarutobi himself?
