Moving to other countries will take time as each country has their own banking/financial/etc issues that need to be dealt with.
It took years for PayPal's Web Payments Pro to go from US only to US, UK. And then a few more years to go to US, UK and Canada.
Amazon FPS has been around for ages and is still US only.
So it may be a while.
