I said that "if we never got a game", that means that AoC happens because Rauru must have vanquished Ganondorf, and Zelda never needed to travel in the past. If we do get a new Musou game, that writers need to have Zelda through Destiny go into the Depths and pick the Zonai Stone.
THE DESTINY will somehow get Zelda to travel in the past either way.
If there is no AoC2 sequel, that that just means that Raura defeated Ganondorf, and Calamity Ganon was just ghost of a long dead Demon King.
