Grey-market importation is a very important right of consumers which allows them to purchase and view works not available in their own territory without the permission of the copyright owner. This is a good thing, especially when there's no real reason for a delay between countries. Many times regions get delayed or inferior releases of content simply because of arbitrary reasons put in place by the owner. This is most a concern in countries like Australia, which are treated like the rest of Asia despite not having any language issues which would preclude a more prompt release.
