I'm not sure I would class some of those countries as 'major' ... but there is a general sense now that bitcoins are leaving the USA, and at an accelerating rate.
I read somewhere that more that 70% of bitcoin transactions are happening in China. So, yes i guess it is leaving the USA.
But there are a lot of bitcoin related startups located at USA. They are open to new technology, build up complete bitcion's infrastructure. There are a lot of ppl there adopting bitcoin. But in China bitcoin is still the minority's game, although 70% of bitcoin transactions are happening in here!
