After almost 7 years of writing and speaking with this Satoshi, I have finally visited and spent several days with him in Denpasar.

My doubts are now down to zero. I can confirm with all my heart that he is the real SN.

By the way - the private keys to his bitcoins were stored in an encrypted file container on his hacked GMX account. He still knows the passphrase, but the hacker doesn't. And he offers the GMX hacker a share of the bitcoin stash if he returns the file container to him.
