Judging by the EPIC classic theme at the end of the teaser, I suspect that Jeremy Soule is still the composer for the game's soundtrack. I really hope so!! His TES IV OST on my computer has over 500 COMPLETE play-throughs per song. That's over 13,000 total song plays! It's actually on right now...

This trailer is completely epic and it gives me GREAT hopes for 2011's GOTY. If the soundtrack is similar, and the magic and awesomeness is similar and everything, just better and MORE, then I will be playing for YEARS to come. Again, SO PUMPED.
I have watched the trailer so many times I cannot even count.
So, please, share your excitement with me!!

EDIT: As seen in this screenshot, I have literally been looping the video for about 40 minutes and just listening to it in the background.

EDIT3: Apparently Viacom "undeleted" the videos as mine is back up and viewable. Strange.
