The fact that Craig didn't go to a media outlet/reporter with any real computer expertise like Ars etc. makes me suspicious (GQ? REALLY?).
He says he doesn't want publicity (GQ?? REALLY?!).
When he was first explored as a potential Satoshi awhile back, when a "hacker" supposedly broke into his computer and leaked emails linking him to Bitcoin, there was reason to believe that it wasn't true.
There is also a tax case and a legal case around this.
"Still, as far as we can tell he indeed seems to be in possession of the keys, at least for block 9. This assessment is shared by two bitcoin insiders who have sat through the same demonstration: Jon Matonis, a bitcoin consultant and former director of the Bitcoin Foundation, and Gavin Andresen, Mr Nakamoto’s successor as the lead developer of the cryptocurrency’s software (he has since passed on the baton, but is still contributing to the code)."

All that's needed is a single signature. Everything about this is absurd. It just seems he's clearly exploiting this to gain some fame to promote his company.
I read that. He doesn't give the message that is signed (just the digest and a screen shot of a small portion of the file). Without the actual data, this can't be verified.
