Confirming it based on the same leaked information which can't entirely be corroborated.

The interesting thing about these claims is that they tie so many parties together, I think ongoing investigations will be able to figure out whether all of this is true.

While so much seems 'too good to be true' and potentially a plant, it is quite incredible that someone would put this all together after the fact to make a perfect fitting story. Either some ends won't meet, or we'll have the answer at long last.

I don't really understand. If he is claiming to Satoshi (as some people have mentioned, although all I've seen is stuff leaked about him) can't he just sign a message with Satoshi's widely known PGP key?
