"One of the most frequently asked questions about SharePoint that we've received since RTM is, "Where is the [this] or [that] Language Pack?" While we still cannot provide exact dates due to variables in our localization and release management processes for different languages, I'm very pleased (and relieved since I'll hopefully get fewer questions now) to be able to provide the estimated release timeframes listed below for when a specific Language Pack will be available on our Microsoft Volume License Services (MVLS) and eOpen websites."
