As mentioned above, it doesn't matter, who cares. At this point, its moot what happened to Satoshi. The damage is done. Satoshi - whether he is gone/captured/still in hiding/whatever - was successful in getting bitcoin out there.
Satoshi is Legend.
Edit/PS: I thought I recall bitcoin technology being useful to the CIA. And wasn't there a story somewhere where the CIA actually uses bitcoin for their clandestine activities? You would think the CIA would appreciate the Satoshi.
