What makes you think that if he reveals himself here in the forum, then he is the real Satoshi? I'm very sure that in the past many people in the forum might have come out to claim to be Satoshi. The only way we can confirm here if Satoshi reveals himself is to make a post if he already have a personal account here in the forum that is verified to be his.
But I don't know why people are always talking about Satoshi revealing himself; I think this is something that is impossible and there is no need for him to reveal himself.
He has a reason for keeping things the way it is right now, who would have known what would have become of him if he came openly to say that he is satoshi, with what we have seen, if anyone comes up now to tell us that he is satoshi, I doubt if anyone will believe him, so I don't think him traveling his identity is even necessary, we are enjoying his innovation so we should keep enjoying that and stop thinking too much, anywhere he is, he will be very happy that his dream is coming to fullfument.
Does satoshi revealing himself matter much like that, who knows he might be doing keeping his identity privately for his own safety.
