A decision was made rather early on that Satoshi-related questions were to be killed on sight with fire and napalm and nuclear munitions. This was primarily because we were seeing a tremendous amount of Satoshi-related questions that were little more than rampant speculation about identity, nationality, where he was last seen and with who and while Satoshi may be a meaningful figure in the Bitcoin world he's not Bitcoin itself and is therefore off-topic.
Similarly, we will kill with fire similar questions about Trendon Shavers (PirateAt40) and other such prominent figures who pull disappearing acts. Questions of this ilk are simply not constructive - and trust me this is the voice of experience speaking.
While this one specific question may actually be answerable, most Satoshi questions aren't and since they tend to bring trouble in their wake, we've declared them off-topic and as such this question will not be re-opened without some serious changes to the current scope.
Currently, we've defined the scope in such a way as to explicitly allow questions about the developers as long as they're actually relevant to the Bitcoin project and have a clear and correct answer. While this question is certainly answerable, it has no bearing on Bitcoin whatsoever. Satoshi is gone and the specifics of his leaving might make an excellent Wiki article but they don't belong here.
