I'd be disappointed that he'd revealed himself. So much of the magic of Bitcoin is wrapped up in his disappearing. The idea of Satoshi is more important than the reality that it was created by a fallable human. Would I sell & rage quit? Nah - there is no alternative. I just think it would be dumb to reveal yourself after so long. Spend some of your coins? Sure - no problems, but do it quietly without endangering yourself or risking the rest of your stack being captured.
