To be honest, I doubt I would notice if it was bad. I'm so excited to play Zelda games, and I always get so wrapped up in the stories and the gameplay, that I never seem to notice their shortcomings. I'm just having too much fun. When I played Skyward Sword, I never thought about hand-holding or Fi's frequent interruptions until I read what critics wrote online. Then I'd think, "huh, they're right, we did spend an awful long time learning how to play," shrug, and then keep playing.
Really, the only way I'd get upset is if the game is so fantastically and undeniably "I just can't take this anymore this game is unplayable" bad that even my very rose-tinted glasses can't overlook its flaws. I doubt Nintendo will make any mistakes that great, though. If it does mess up, it will probably be something small that I won't notice while I'm playing and won't care about when I do.
