The first game Falcom handles like that will be the Switch version of Nayuta no Kiseki Kai (The Legend of Nayuta: Boundless Trails).
The latest game in the long-running JRPG Trails / Kiseki series is The Legend of Heroes: Kuro no Kiseki, released in Japan on PS4 on September 30, 2021.
Besides the next Kiseki game getting released by September 2022, Nihon Falcom also mentioned in its financials plans to start in-house development of games on Nintendo Switch (Thanks to Game’s Talk for pointing it out).
Falcom developing on Switch from the get-go means higher sales for its games, as future Kiseki, Ys, and other games will be released simultaneously on PlayStation and Switch from the start.
