Will this track be put in to skyrim? http://www.youtube.com/watch?v=xz8uG0Av4KE&list=PLC9AFDE310DD60AE4&index=116

Probably in one form or another. It won't be an exact carbon copy, though, as the entire soundtrack is designed to make you feel like you're in the land of vikings.

I dont know but in the Skyrim demo they had a track from Morrowind playing, but I do not know if it was just a place holder

I believe something very similar bc during the demo it sounded a lot like the track in the OP.
