I think he (she,they) will never reveal his identity because he will have no life anymore. So much people, journalists, talkshows etc worldwide want to speak/meet with him.
Besides that what do we gain with knowing his true idendity, his legacy is more important, and what we do with it. If i place myself in his shoes now i imagine he would
be sad seeing what is happening with his project. Regulation, futures, hacking, scamming, ICO's and i can go on....
The only thing he would be smiling about is the adoptation of Blockchain technique in the old economy. Just my two cents...
