Well I guess http://www.youtube.com/watch?v=MjbfLaOjgzg&feature=channel_video_title#t=2m56s confirms that some finishing moves do in fact bring you into a third person perspective regardless of the player's preferences. A fear that many people had since yesterday when Dovahkiin killed the dragon. I think it's awesome how they happen in slow motion like VATS from Fallout but I know not everyone will enjoy being tugged out of first person view.
