Reminded me alot of Morrowind (duh) during those panormas, compared with Oblivions versions, which was great but different.
Well the music during the panoramas was the elderscrolls theme, which was the main part of Morrowind's theme and also was in Oblivion's theme and now in Skyrim's. Also the music in that video had Oblivion music in it as well, at the end of the trailer as it moves from the dovahkiin absorbing the dragon soul to the mountain valley with the dragon flying across it.
