Bearing in mind in the UK we're STILL waiting for iTunes radio, I'm not holding out hope for the foreseeable future!
There seems to be a major problem with Apple and international rollout for services, you only have to look at the crippled Apple TV in the UK to see that.
If Apple roll out a new service saying rollout in the US first, as I rule I generally try to ignore it all together.
Still, at least they get their hardware out at the same time as the US! 😀
