During the Microsoft keynote at MWC, it was confirmed that Windows Mobile 7 will indeed have the Zune service integrated. Containing Music, Videos, Podcasts, Radio and the Zune Marketplace, this surely means the world-wide release of the Zune services.
In Australia we can of course download the Zune application, or rent movies through Zune Video marketplace, but if you wanted to use Zune Maketplace to purchase your music or videos, your out of luck. For the new Windows Phones to seriously compete in Australia, where smart phones have been very successful, the full Zune service (hopefully including subscription-based music) needs to be available.
