The Memory #1: Subdued Memory (part of the Main Quest) explicitly mentions Skyward Sword, Ocarina of Time and Twilight Princess as previous heroes in ALL languages.
Any other a-hole claiming it says something about "the seas" in another language is plain illiterate in all honesty, I have verified all languages in the game and their text, and they always mention those three.
That's a pretty solid evidence to start with.
There is more, and I can go on for a while but I don't want to write as much using the touch keyboard on the Wii U Gamepad
