Yeah, but if you look at the graphical styles from the beginning of the series, Wind Waker is closer to "traditional" than OoT was. The only other game in the series besides OoT and Majora's Mask that tried to make the graphics more "real" was The Adventure of Link, and that's the most "non-traditional" Zelda game ever.

Wind Waker was more traditional because Link has always been portrayed as a cartoonish character. LoZ, A Link to the Past, Link's Awakening, Oracle of Ages/Seasons and Four Swords have all shown link to be a cartoony character, not a hulking badass with a giant sword. OoT was non-traditional, not Wind Waker.
