As "Nice Try" mentioned above, this is 100% fake. This sort of irresponsible "journalism" is just embarrassing... I mean, they were already fooled once by Wright's obvious fakery.
It is strange that someone who boasts a fairly impressive technical CV like Wright's, would put himself in the position that he has if he can't 'prove' his claims to be true by signing relevant messages. If that would be sufficient proof for the community, that is.
IF he is Satoshi, or an element of the original group, his motivation for coming out could be one of a number of reasons, but
this sounds like he's not planning on going quiet into the night with his coins.
A new forum.... coool, I wonder if he'll have sig campaigns, ponzis and all the essentials that we know and love?
Until then, see my new sig....
