Trust me Jekyl. When KYF posts a wall of text that it's filled with mistakes, you try to get better at using the correct form of English, even if it's not your first language. Simply, it motivates you when you see his fail. Check my signature. It contains the best example of KYF's stupidity.
And about the theory: i don't think that it's plausible. Kishi wouldn't hide Tobi's face behind a mask, if he wasn't someone that was introduced in the series. Most likely he is someone from Konoha, that had ties with the Kages and the Uchiha clan.
