Games are rarely dubbed in continental european languages, even German voice acting is very rare, Munkeh. As a Swiss, I'm used to subtitles cause in our theatres, movies are usually played in english with german subtitles. I don't know how it is for Germans though because they use to watch their movies in German.
And to come to the original post: I think this will cause some frustrated users, but not in a measurable number. It sucks for those that will be put off, but it won't be as many as it could cause an economical issue.
