All the evidence so far is speculative. To reveal the identity of Satoshi Nakamoto really need to make a solid connection between him or her and his work in Bitcoin. They may appear as links to the real identity behind bitcoin.org domain registration, e-mail accounts or forums, that Satoshi Nakamoto used them, or that has at least some of Bitcoin first herded.
It seems that neither collaborators at the beginning of the project have solid evidence regarding the identity of Satoshi, so only time will tell if such evidence will be discovered or if Satoshi himself / herself will unveil its own identity. Until then, we can only play mafia, identifying a programmer or another, without even have safety ... if I guessed it would return the book and tell us that we won.
All we can say in the end is that if Satoshi Nakamoto is out there and read our articles, we ask to contact us and tell us if we got the real version.
