For me, the graphics don't really matter as much. It's more the overall game play and just how enjoyable the game is. I really liked Wind Waker, and certainly would play a new Zelda game even if they did do cel-shaded again. I think it would bring a lighter feel to the game. Now, if they are going for a darker feel, I don't think that the happy cartoon-y graphics would be the best choice. It really depends on the story in the game. Like, if in Twilight Princess, they tried the cel-shading again, it might not have been as dark as what they were going for.
