We talk about personal preferences here, but I still think dubbing it to different languages would bring in more money than it costs. Many folks are way more comfortable when games/movies are in their language. In the USA they even remake movies, so they don't need subtitles.
I am comfortable with subtitles myself, when I don't understand the language, but it's pretty irritating for me, when I hear them speak in English but read it in German. So when I played PoE for example I just turned off the English Dub.
