So are the Snow elves making a comeback? Or do we get to somehow re-live the Nord/Snow-Elf war?
Some more speculation, perhaps we go to the Snow Prince's island of Solstheim?

Also:
It was Nordic tradition to burn the corpses of their foes, however it was decided that the Snow Prince, who was so loved by his kin, deserved better. Instead the Nordic chieftains honored him by having his body wrapped in fine silks and buried in a freshly dug barrow[1] that later became known as Jolgeirr Barrow[2].
