I'm pretty sure The Wind Waker HD remake indicates the "real" Wii U Zelda will have a completely different art style.
Because they mentioned the main reason the WW HD remake even exists is because they were experimenting with old Zelda art styles on Wii U, so this sounds like they liked the cartoony style, but liked something else better (likely a more realistic style).
So the cartoony style gets brought back for the Wind Waker remake. The proper Zelda will be different.
