Nah, I do not think that it will move the market, we all know that Satoshi will not be identified or even if whoever they say they found out who Satoshi is, as Bitcoin enthusiast, we will take that with a bag of salt.
And even before, when people says that they found Satoshi, it didn't affect the market that much. Maybe it will open the eyes of some non-crypto person, but it doesn't mean that they will instantly buy the hype once again.
