If you were Satoshi and had half a billion dollars in assets, but knew that touching them would make their price drop by 80-90%, what would you do? You would almost have to reveal yourself publicly, if for no other reason than to reassure the community that you aren't going to sell everything all at once.
I think I would gradually introduce myself to the world in much the same way CW has...
I would make a case based on circumstantial evidence that, upon further examination, doesn't appear too reliable. But at least it gets people thinking that maybe, just maybe, Satoshi is still alive and could theoretically move his coins. Among my circumstantial evidence would be a trust agreement showing that I can't move the coins until 2020, so that people don't freak out if for some reason they do believe me.
Then I would meet privately with some trusted community members and get their imprimatur, then post some shady shit on my blog. Gets people thinking even harder, but the rest of the community still doesn't believe.
Then I would move a coin from an early block which can't definitively be linked to Satoshi. More people would believe me, but the majority would still say "somebody else probably mined that one."
Then maybe I'd get different trusted developers to come for a private meeting, and sign something with Genesis but forbid them from releasing the signature...like CW did with Gavin for Block 1.
Then I'd just keep going until eventually I proved myself publicly and announced that my coins are locked down for the next four years, and that even after that I will only be able to spend X coins per year.
If he does, then wow...
Remember, Block 1 was not necessarily mined by Satoshi. I wonder why he isn't using the Genesis block? My guess would be that somehow he either mined or acquired the keys for Block 1 from somebody (and is not Satoshi), or he is Satoshi and Dave Kleinman maintained the privkey for Genesis and never gave it to CW.
