I think the OP is mistaken when saying that HD does a disservice to cell shading, and I agree with others who see this upcoming version as using a similar, albeit not identical style to Wind Waker. Just check out 1080p pics of Wind Waker on the Dolphin Emulator. Infinitely more clear than the jaggy stills used to show the gamecube graphics, but not one change in style exists because the graphics are ripped directly from the gamecube rom.
I agree that old STYLE is better, but this re-imagined Wind Waker still looks great!
