In the official roadmap, the german translation seems to be prior:
Strings localized into various languages.
* Q4 2008: German
* Q1 2009: French, Italian, es_es, zh_TW, Ja, NL, CZ
So eventually the G1 is released in germany in the early Q1 2009 if the translation is finished in 2008?!
And not all across europe at the same time as exspected so far.
Of course this is just a rumor. But it let me sleep a bit better now
