I'm really eager to see how conclusive the study will be. For now, I'm sold on Satoshi Nakamoto being King, Oksman, and Bry. http://www.fastcompany.com/1785445/bitcoin-crypto-currency-m...
Here's a quick litmus test when someone proposes a Satoshi candidate X: "how did $X pay for DigiRock hosting of bitcoin.org in August 2008 when DigiRock accepts only yen and has no English language support?"
Only yen could be worked around through a prepaid card, stolen card number, gratis account, and probably other methods I'm not aware of.
Lack of English support doesn't necessarily make the person Japanese. Westerners can learn Japanese or use translation tools.
