If Satoshi has ever been identified, Bitcoin will have a huge impact. It will be one of the biggest news in the history of Bitcoin and this could have a positive effect on the price of Bitcoin. That's my own viewpoint, but I see it's going to bring good news. Everyone would be excited with the discovery of the Creator's identity, but for Satoshi, it might be difficult for him because he might be threatened by those people with bad intention and the government that will prosecute him and so on.
That is why in the very first place, he already know what to do and decided that for the common good, being anonymous which is in fact he also provided others as well, is the best thing he did to himself. With this, he detached himself from the influence of the world, and to completely not affect the market condition, in which, people who utilizes bitcoin received the freedom to decide for themselves and to decide what would be the best for the market. Now, we are abiding the system, and for sure, he's doing the same thing but with a bit of advantage of having the fruits of his labor, a couple of BTC.
