Wow. Unexpected surprise from Nintendo...
I vaguely remember a couple of people who were a little put-off after hearing that Zelda: Wind Waker (or whatever it was called at the time) would be cel shaded ? a drastic change from the short clip that was shown at Space World 2000 that showed a fairly gritty and realistic battle between Link and Gannondorf.
Now we've all been here expecting the sequel to Wind Waker to look very similar to its predecessor (since Nintendo claimed they'd be using the same engine), but they've gone and switched things up on us again. Looks like they're going back to a more realistic look, which is great by me (not that I disliked the cel shaded graphics, I guess I just prefer this more realistic style)!
