We here are all user volunteers with no special insight to Apple's plans
That said, Apple supports technical "questions" via Twitter - https://twitter.com/AppleSupport - with the same level of expertise that they do via telephone and chat in its major markets like the USA
Regarding "service" of devices, there are many countries throughout the world where Apple does not provide repairs - even through Apple Authorized Resellers & Service Providers today. I am guessing that any repairs done in these countries would necessarily be "black market"
One good question would be about "stores" - Apps & music -
In countries with no official Apple presence, these services are not available today - will Apple "close" the App Store in Russia?
You could contact Apple Corporate and ask them, but Apple is notoriously tight-lipped about future plans
