Lets stop hoping on what is not possible, because he cant reveal his identity, assuming he wanted to do so, then he would have done that a long time ago, he has always preached about privacy and cant be the first to violet on that on himself, many have been talking all manners of talks on the internet about his identity, which they are more optimistic to know, but the truth is that, Satoshi cannot be seen publicly by his identity.
As much as I believe that he wouldn't reveal himself, nothing is impossible. But your argument about Satoshi being a proponent of privacy is strong. He invented a decentralized currency to make financial dealings private; he would always want to remain anonymous. There are also possibilities that he is not alive because he is not immortal.
Honestly, I think a lot of people don't give a damn anymore about his face. Bitcoin has been able to sustain itself till this moment without his further input. I think it should remain that way. His sudden appearance will definitely shake the market, whether anyone admits it or not. There's going to be selling pressure if that happens. We're better off now without that revelation of the person of Satoshi.
Bitcoin is now bigger than its creator. The major concern people have about Satoshi is not seeing his face but the amount of Bitcoin in his custody.
