Bad news. Jeremy Soule is doing EQN so likely wont be available for this ES. Any word what they will do instead?

Jeremy Soule was actually confirmed to be involved with the soundtrack. http://elderscrollsotr.mymiddleearth.com/2013/03/25/zenimax-online-eso-skyrim-composer-jeremy-soule-confirmed-to-be-involved-with-eso-soundtrack/

That is great news.

Besides it was confirmed officially.:

I saw some footage of gameplay the other day and was particularly impressed by the soundtrack. Really skyrim-ish in its feel and very high quality.

You could hear the Soule-soul out of it. We can look forward to it.

Any info if music from previous titles is used? It would really add some nostalgy to the game.
