The dragon shout don't do a thing for me. Well, aside from making me cringe at the slow creep toward a voice-acted player character. :shrug:
Your character's always been voice-acted. Grunts count too.
And yes, embarrassing as it is to admit it, I watch the damn trailer every day. The music is awesome, especially the crescendo as the main part gives way to the dovahkiin chant. My favorite parts are the actiony bits. The combat looks much meatier. I can't wait to play the game.
