Yesterday MS has released the language packs to the public. What is a language pack?

Language packs enable site owners and site collection administrators to create SharePoint sites and site collections in multiple languages without requiring separate installations of Microsoft SharePoint Server 2010.

Word breakers and stemmers enable you to efficiently and effectively search across content on SharePoint sites and site collections in multiple languages without requiring separate installations of SharePoint Server 2010. Word breakers and stemmers are automatically installed on Web servers by Setup.

The server language packs:

2010 Server Language Packs for SharePoint Server 2010, Project Server 2010, Search Server 2010, and Office Web Apps 2010

And if you have a plain SharePoint Foundation installation, grab the language pack here:

Language Packs for SharePoint Foundation 2010

After you install a language pack, you’ll need to rerun the configuration wizard.

And here is an important information which is different from previous versions:

SharePoint Foundation 2010 language packs are not required for SharePoint Server 2010.

Finally. Handling language packs is now much easier :-)
