Apple's new iPhone Developer RSS Feed brings world that iTunes Connect now supports Brazilian Portuguese, Korean, Portuguese, Simplified Chinese, and Swedish language localizations:

With over 50 million users of iPhone and iPod touch in 81 countries around the world, it's more important than ever to make your app available in a user's language of choice. You can, and should, create localized versions of your app for each market you sell to. In iTunes Connect, you can customize your app's metadata, keywords and screenshots for each localized version.

So if you're in one of those countries, head on over and give your local App Store some linguistic love.
