On their website, an 'Urgent Recruitment' page asks 'Would you like to make a legend together 2?' Grezzo, the Japanese game studio that developed Zelda: Ocarina of Time 3D, Majora's Mask 3D, and Tri Force Heroes, have put vacancies for Programmers with experience in Unreal Engine 4 on their website.
Koichi Ishii, the president of Grezzo, was the game designer on the original SNES version of the game, Seiken Densetsu 3. Alternatively, it's also possible that they're the studio behind Trials of Mana. It's possible that this was the game they were hiring Unreal Engine talent for. Update: Grezzo has been revealed as the developer behind the Link's Awakening remake for Switch.
