New english spoken conversations in non-english language versions

I have a question to BG:EE developers - how are you going to address the issue of new english spoken conversations in non-english language versions of BG:EE? I'm pretty concerned, because it might be somewhat annoying to listen - for example - to polish voices in 90% of the game content and to english voices in the remaining 10%.

Are you going to disable new untranslated content in non-english language versions by default? At least please provide an in-game option allowing to do that...
