Why does Nintendo not use the twilight princess graphics style on other zelda games?

i have noticed the Zelda games that are being released are looking more like wind waker. these graphics are nice but i miss the twilight princess style of graphics. why dose Nintendo go with the wind waker style? and what do you think? would you rather the graphics style seen in twilight princess or the graphics style used most often today in zelda games. best example of what i mean is the skyward sword previews.
