I'm playing 1.5.0.8, English version. It shows EN on the options page. All printed materials are in English, but the voices (at least, the voice of the first character I meet) are in German; is that expected?? I was reading another message here which seemed to suggest that this was how it should be, but would like to confirm!
Yep, that's how it should be. 
Is there a way to turn on English subtitles for in the game itself? I'm in the first quest at the beginning of the game and I can't understand a word this guy is saying and there isn't a subtitles option in the menu.
Never mind I found the subtitles, they were in Game Options.
