Nintendo has moved towards 3D games with the Zelda franchise on consoles, but it's possible 2D titles could be released for the Switch. Speaking with Game Informer, series producer Eiji Aonuma said it remains a possibility that 2D-style games could be out at some point.
He said the teams behind 3DS Zelda games like A Link Between Worlds, a 2D-style game, could work on 2D titles for the Switch.
The 3DS team and the Wii U team have different approaches to game development, so I don't necessarily want to combine them and have them think together, but rather have each think about what they can bring to Nintendo Switch from their own perspective, - Aonuma
Initially, The Legend of Zelda: Breath of the Wild (a 3D game) will be available for the Nintendo Switch.
