On the issue of international availability of the Blizzard Authenticators, as reported by MMO-Champion, this came from a blue post:
“We’re also aware that non-U.S.-based players on our North American realms were unable to purchase the Blizzard Authenticator from the online store when it was available. This was due to shipping-related issues with our store for this device that could not be resolved by the time it first went on sale. Rather than delay the launch, we felt it was important to make the Authenticator available to as many people as possible as quickly as we could. We’re continuing to work on a solution for these players and will provide an update as further progress is made.”
I don’t see what’s so hard about the “solution” of shipping overseas – I hear the postal service has this thing called ‘international mail’ now – but I’m glad to know they’re not deaf to the issue, at least.
