I'd guess the other half is going towards things like localizing text and dealing with getting the device certified for the market, etc. You could say the same about the initial English version and USA certifications - but those are generally bundled into the core product while the German part would be extras. Yeah that does mean you're paying for both the English version and USA certifications when you buy the device in Germany even though you aren't using those, but that's life.
