Actually, and I'm sure this is intentional though they've never come out and said it, I think the cel-shaded style is now reserved for portable Zelda games and spinoffs like Four Swords Adventure(s?). Honestly, that's fine with me--and besides, from Nintendo's point of view, it's probably a better way to draw in the casuals.
As for Minish Cap, that's technically part of the Four Swords series (it was made by Capcom).
