Judging by some research I've done, the names are likely to be Nordic/Scandanavian as apparently the Viera from XII were given Icelandic accents (specifically with Fran) and the names seem to match that kind of style.
I can't say for sure, I'm not remotely clued up on Icelandic names. But I think it'd be a safe bet to assume it for a baseline. As nothing was noted in the live letter last night, I will guess we'll be waiting until next week or the 27th for the real naming conventions. I've got a feeling they might be snuck in with the Pixie language thread.
