Still no iTunes Radio for UK, Canada, Australia and other countries.

I was wondering, while I was reading the article, why doesn't UK, Canada, Australia, and all the other countries, still do not have iTunes Radio?

This kind of puzzles me in a sense, because I would think that Apple would be losing a lot of business and consumers. Also, I bet a lot of music lovers in the world, might be upset about this.

From my understanding, there is a lot of people from these countries that have been waiting for a long time, for the iTunes Radio app, to come out.

Correct me, if I am wrong!
