They should focus on gameplay and the story instead of making the industry more and more complicated. But since gamemaking is now an standarized industry they focus on stupid issues like foreign languages. I can't speak for everyone but even non speaking english/japanese players probably prefer the original vocal language with the subtitles in his language. For instance I speak in spanish but I cannot bear to hear spanish from spain, nor mexican, chilean, perubian, bolivian, etc. So I only play games in english/japanese with subs. So why bother ?.
