At this point, I wouldn't be surprised if Nintendo tried to buy Grezzo and make them one of their subsidiaries along with Monolith Soft, Retro Studios, and Intelligent Systems.
They could take over development for the top down 2D Zeldas (Link to the Past - Link Between Worlds) and old school 3D Zeldas (Ocarina of Time - Skyward Sword), while Nintendo focuses solely on the Open World Zeldas (Breath of the Wild).
That would be their Nintendo franchise that Grezzo works on (like Paper Mario for IS) along with their own franchise (like Fire Emblem for IS or Xenoblade for Monolith), it could be Ever Oasis or it could be another IP.
