I think If Satoshi reveals himself, their will be no changes to bitcoin, except he start selling his Bitcoins (1 Million bitcoins) that will just
make bitcoin have no value, it will shut from current price 900$ to .9$ so I think its a good point for Bitcoin that Satoshi is now hidden in some where

I think the price would see a change if satoshi revealed itself... it's a big psychological factor. It may not mean anything by itself, but it opens the possibility of him selling. Right now everyone has assumed that he is just dead, but if he proved he is alive, the doubt of his coins being locked forever would end, and the possibility of a selloff could happen.
