That's very hard to say or determine, because no one has heard from the creator over a long period of time, I think he's or perhaps the group is acting behind the scene so as to ensure that the market is free of manipulation and its 100% free of manipulation. If Satoshi shows up today, he would be taken as the messiah of bitcoin and let's say one  day he says he's withdrawing 100 BTC from his wallet, that would force people to also withdraw thinking the market might crash, meanwhile it might not.
