Gibdo: I noticed all of those references, too, about the difference between OoT and WW being much more than 100 years (especially since if Medli, a bird like Rito, is the blood descendant of the Zora sage of the Earth temple- it would take MUCH lnoger than a century for a being to evolve that much), and since Link from OoT is already a legend, which takes lnoger to formulate than a mere 100 years. But if you look at the opening scene, it says that every 100 years a new hero is born, which heavily implies that the Link of WW is the next Link after the one in OoT, and the fact that they worship the Hero of Time so much means there haven't been any Links inbetween OoT and WW, placing WW 100 years after OoT. Very confusing.
