Pretty much the opposite for me, 99% of the time I use Scandinavian layout and only when there's some compability issues i revert to US layout. Anyway, hope to get some official answer what the options will be, if there will be any.
Here to join with a vote for scandinavian layout. Right shift is not needed so EskeRahn layout mockup is better. Letters could have a print with æ/ä, ø/ö and å. æ/ä should be on the right side and not left imho.
