It is clearly obvious that Craig Wright will be accused of identity theft by many if he really provides the crypto proof he announced yesterday.

Too many people prefer to think of Gavin Andresen as a complete idiot easy to fool with some stupid tricks or even a fraud one can buy, rather than to accept Craig Wright as Satoshi Nakamoto. They also think about Craig Wright as a complete idiot who gives false proof easily debunked in a matter of a few hours, when he never ever stated that his discussion of "Key Verification" was a proof of anything.

So if he is who he claims, which is something I don't know, then he has good reasons to try to proof it far beyond a signed message. The signed message, if it appears, won't settle things for him. Many people will just say he had the keys stolen.
