Yes, that might be true. While I worked for the Danish Tourist Board a few decades ago, we actually had material printed in "Scandinavian". However, that is also the last I have heard or seen of them that actually reached out to Joe Public. They seem to me to be as successfull as those who kept telling us that the language of the future would be Esperanto. For comparison: In the meantime there are more people in China who can speak English fairly well than there are inhabitants in the USA.... I hear that there an institution (in Danmark if I'm not mistaken) that is working on a common scandinavian linguistic norm for all 3 countries. I for one like the sound of Danish the way it is. I would find it a pity if a supranational scandinavian norm were to crush the lignuistic "national norms" of those countries.
I wouldn't expect to hear more of this "Scandinavian" language, if I were you.
