I agree with Serinox. The parallels to Spectre are very interesting, but if there was any theory proposed about who Anokata is, I missed it. Unless you're suggesting that Anokata is Blofeld, in which case I must say that, while that would be interesting, I don't think there's any more chance of that being the truth than there is of it being James Moriarty. Good fanfic material, but I don't see Aoyama-sensei going that route.
