It's entirely impossible that Satoshi's true identity could be revealed in the future but at this stage I would say it's unlikely. If he/she/they were to make a return then it would be interesting to see how the community would react and how much influence could be had.

I don't really think it would make any difference to the price unless it was something outlandish like that the FED created bitcoin.

I believed that though the founder will reveal himself or themselves they might affect the price for a very short time unless they will make bitcoin better (faster transaction and lesser fees). We can see that many are still wanting to know who created bitcoin, I guess future will tell us so, but for the meantime we just need to be contented that we have bitcoin and we are earning from it, and it is changing the financial world big time. 

It's totally impossible that Satoshi's identity would be revealed. He'll be ambushed if it ever were.

It would certainly be interesting to see the true identity of Satoshi, I'm unsure it would change the price though

If we Satoshi Nakamoto would himself/ herself, it wouldn't probably impact the community. Yes, we are all eager to know the person behind this concept, but then, what? Will it convince more people to join the community, which will lead to increase of demand?

either way it doesnt affect much in long term. bitcoin doesnt belong to the founder anymore.

Yes it will be very difficult to introduce btc to people back then, I was not really believed in bitcoin back then, I thought it was some scammed investment, but after few proof by my friends I decided to try, I dont think Satoshi will revealed himself, there will be a lot of people target him if he revealed his identity, the government will want to taxed him and the criminal will want his money, I believe the concept of bitcoin was not created by single people since btc is a very complex thing
