Zerlan hasn't often been accurate in his estimates of things.
I'm not going to bother to link to these because a quick Google search can turn up the evidence.
Nakamoto registered the bitcoin.org domain on a somewhat obscure Japanese site. His communication in English had all kinds of clues that his native language was Japanese (sentence structure, word choice, etc.). He was active during daylight and evening hours in Japan.
I really wish people would stop speculating who he is. It only matters to those who can't read the code and understand that it ultimately doesn't matter, except the possibility that he may one day "come back" and have several hundred thousand Bitcoin to himself. As benevolent as he acted, it's unlikely that he'll pull a Biff Tannen and rule the world. However, miners have the power to stop him if he tries.
