Good news for those of you who haven't yet been able to grab an authenticator -- the units are back in stock at the Blizzard store (for both the US and Canada, Australia, New Zealand, and Latin America, with the EU version available over on their store). The price remains a cheap $6.00, and this latest version features art from Starcraft II.

Which, now that I think about it, pretty much confirms that it will work not only with World of Warcraft, but all Blizzard games going forward. Obviously, with Starcraft II not even in beta yet, hackers and scammers aren't exactly targeting it, but Blizzard is thinking ahead, so if you don't have the tech yet, now's your chance to pick it up (at least until they run out of stock again).

And don't forget -- if you don't have an authenticator yet, but do have a compatible mobile phone, you can always pick up the Mobile Authenticator. Especially if you have an iPhone or an iPod touch, free is the way to go.
