Monolith Soft is lending a helping hand in the development of The Legend of Zelda: Breath of the Wild, Nintendo's Shigeru Miyamoto has confirmed to Game Informer.
"Yes they are involved in this Zelda. People from Tokyo and Kyoto are working together on this. There is a team of over 100 helping work on this project, and their work has really been helpful," he explained.
Xenoblade Chronicles X directors Tetsuya Takahashi and Genki Yokota had said last year that the team at Monolith was interested in helping develop the new Zelda, having previously offered assistance on Skyward Sword.
The Legend of Zelda: Breath of the Wild will launch in 2017 simultaneously on Wii U and NX, though it's not yet confirmed as an NX launch title which arrives in March.
