A quick update on how the download language can be set in the MSDN Subscriber Downloads site. Currently, there is a language pull-down box in the site header that can be used to select a language. This pulldown is going away, and there are two main ways to select your UI language:
1. The localized MSDN regional sites will link directly to the localized Subscriber Downloads registration and login pages.
2. After logging in and going to the Subscriber Downloads benefit, you can select your language in "Download Preferences".
Our new language options will be Japanese, Korean, Simplified Chinese, and Traditional Chinese. We have preliminary plans to add European languages (probably German, French, and Spanish), but this work has not been finalized as yet.
