Sergio Lerner has spent more time and effort than is really healthy tracking down which Bitcoin addresses belong to Satoshi. You can read his opinions, and his reasoning/methodology, here.

As best he can make out, Satoshi has something 1.14M bitcoins.
As such, Satoshi has already made history, back when Bitcoin was poking its nose above $1000 per coin, as the first anonymous billionaire of the 21st Century.
But as far as I could tell, he only mined to secure the blockchain. I don't think he has any interest in those coins.
I wish someone had an estimate of how many of those coins did satoshi sell.
