After Nintendo showed the trailer for Breath of the Wild’s sequel, eager fans speculated that the tone possibly suggested that it’s related to Ocarina of Time’s direct sequel — Majora’s Mask, or that the Mask would be in the game itself.
During an interview at the Nintendo booth with IGN, Director and Producer of the Zelda Series, Eiji Aonuma, confirmed that the sequel will not in fact be related to Majora’s Mask, despite the darker tone.
“The new Breath of the Wild or the sequel to it, it’s not necessarily going to be related to Majora’s mask or inspired by it… What we showed you currently is a little darker,” Aonuma said.
