How has Wright been supporting himself? He owns 3 properties in various locations in Australia.
If he is Satoshi he has access to an unbelievable fortune!
He's got kids - are they in great school (who wouldn't spend money on their children's education, if they had it?)

If he really was Satoshi and didn't want it known - then he shouldn't have done that panel shown in the video. Or he should have had a cover story ready instead of dropping "I am Satoshi" hints left, right and centre.

Why did he go for a Japanese name? Does Wright happen to be a huge anime fan, and fluent in Japanese? Or maybe he has some other connection to Japan?   Check his Facebook.

Satoshi's writing has been with Commonwealth spelling, not US. That supports his being Australian. Of course, it could be "planted" but the comments in question were made long before anyone had any hunch Bitcoin would take off.

Seems he's close to the heart of Bitcoin either way.
Perhaps he was number 2 in a duo headed  by the guy who died.
