Nope. It would finally put any doubts to bed but I don't believe it will ever happen. The idea of someone like Satoshi handing over his wee driving licence to sign up to Coinbase is about as likely as Donald Trump organising a photo shoot with him wearing a nappy and playfully wrestling leathermen in mountains of bubbles.
Perhaps, or it was a private decision taken years ago, maybe tied to the disappearance of the character. What decision? Losing the wallet private keys on purpose (burned coins). Or perhaps its in a time capsule of sorts. Could be a grand master plan, someone could suddenly become world richest person...
Whatever the case if there is no turning back then it might be for the better. Just look at all the drama with the faketoshis. Would there be friction with the current developers?.
