The Falmer are out now. How it's clear to you ^_^. If you figured it out I'm glad you know how to solve a simple riddle. If you haven't
A riddle would imply that there were clues given, that based from them alone, it could be solved.
However, based on all the OFFICIAL information, and OFFICIAL screenshots, there is nothing mentioning Snow Elves. And based from lore they are pretty much extinct. Barring what blue-skinned creatures that have been seen in past games that are RUMORED to be distant relatives of the Falmer. Of which no proof has been provided. Only in-world speculation.
EDIT:
All we have is speculation on Dwemer, or Dwarvers from the screenshot that appears to feature structures similar to theirs.
