Not a fan of first-person shooters, myself. They give me motion sickness. :c
That being said, I wouldn't mind if Nintendo made a spin off mini-game (similar to Link's Crossbow Training) with this mechanic, but if they produced a complete title in first person, I'd be pretty bummed.
Third person shooters...
Well, since Zelda is open to change, maybe they could at least give this a shot.
