While not many people here complain about the cel-shaded Zelda, I think that "realism" isn't what Zelda is all about. I much prefer games like RE, Metroid, or MGS to have a "realistic look" to them then say Mario or Zelda. The main point is old-school, and characters. When these games were released, the characters were super-deformed to match up with the pixels of those days. That's the reason Mario wears a hat, overalls, and a 'stache. If Mario was changed to fit a "realistic" look, then it wouldn't feel like Mario. The same with Zelda. Link needs to be friendly and fun, not scary and macho tough-guy. If the "realistic look" was to be in a Zelda game, I think they'd have to remove "Young Link" from the picture, like the remove "Adult Link" from Wind Waker. Perhaps the as of yet maybe "realistic" Zelda will be a sort-of follow-up to Wind Waker, changing styles to suit the story and gameplay. Who knows, only Nintendo and time can tell.
