I've had lots of time to think about this, as have all of you and a couple of things stick out to me:
1. He wouldn't sell his coins - even if he has the private keys, he didn't create Bitcoin to become rich. Bitcoin is his baby and he knows what would happen if he ever put any of those coins on the market.
2. He obviously has a background in Hacking and Cryptography. He probably made a decent living before he created Bitcoin and probably continues to do the same.
3. I used to think maybe he ended up in jail but the day he came out of the shadows to renounce newsweeks claim proves that he either is not OR if he is, Satoshi Nakamoto is part of a team and therefor could act as satoshi even if the real one was in jail. I doubt jail is likely.
4. I would guess that he is living a normal life, he bought some asics when they came out and probably has a hefty sum of personal bitcoins that are not the ones everyone is watching..
5. Possible scenario: He was already working as a securities expert or systems administrator. Gavin tells him he is going to the C.I.A. and Satoshi has a realization; he has to disappear. He counts his Bitcoins to date as a necessary evil and locks them away, possibly throwing away the private keys.
(If he was in anyway doubtful about the C.I.A.'s involvement or intend -this is how I would've handled the situation)
He throws away anything linking him to Bitcoin, moves, starts a new job as a securities expert or consultant. And gets back into Bitcoin, this time appearing as a novice. He starts mining again breaking up his transactions and wallets to smaller numbers so he doesn't have all of his eggs in one basket. And he moved on.
Now he is one of us, or at least appears to be. He lives a different life now, knowing that he can never touch those coins but in the past years has built back a large amount from "hobby mining". He attends the conventions. I'd like to believe that whatever company he works for was probably one of the first security companies to enter the arena - that is where I would expect to find him.. The thing is now, even if he was to reveal his identity no one would believe him. He has shed A LOT of the evidence of his "Satoshi Nakamoto" pseudonym.
