that's what i thought, too. i'd also like start to translate the files into german. even if there are changes until the stable version will be launched so we would be able to have translated most of it and just have to add, delete or change some of the languge keys.
I know D7 still under development, but Boonex should provide to the comunity the language file so we can start to translate it.
That would make non english sites using D7 more fast to be online after upgrading
