I already read somewhere Myamoto (creator of Legend of Zelda) stating Minish Cap occurs before Ocarina of Time. But of course, they already happened to state things they denied afterwards. I guess Locke is right, their attempts in creating a game change through the creation of it, though maybe the creators still talk of beta elements when they're in interview.
The legend at the beginning of the game (The Minish Cap) has interresting things to tell us :
A long long time ago...
When the world was on the verge of being swallowed by shadow...
The tiny Picori appeared from the sky, bringing the hero of men a sword and a golden light.
With wisdom and courage, the hero drove out the darkness.
When peace has been restored, the people enshrined that blade with care.
It is to be noted that the sword in question had a blue-purple hilt. I don't know what they meant to do with that game, but...
