Having the option to choose between both would be nice (I can't imagine the audio files taking up much space—they sound so crappy), or having English subtitles for the Japanese and original German intro.
It won't ever happen that way, though.
I just wish there were no regions when it came to downloadable content. (Well, regions in entertainment should disappear, period, but whatever.) If I want to download Japanese Virtual Console games, I should be allowed to do so, legally and officially, on my US Wii.
