For fields of mistria switch, NPC Studio's FAQ currently lists Windows PC availability and Steam Deck compatibility, while the press kit lists PC: Steam and Console: TBA. Neither first-party page names Nintendo Switch. Wait for an NPC Studio announcement and a matching Nintendo product page before making a Switch purchase, price, save-transfer, control, or performance plan.
Current official answer
NPC Studio's FAQ says the game is available for Windows PC, is Steam Deck compatible, and that the studio will evaluate potential ports later. The current press kit names Steam for PC and leaves its separate console line at TBA.
Use Steam only for the available PC edition.
Official platform record
The press kit's named PC destination is Steam, and the Steam product page is the matching PC storefront record. Steam lists Windows and SteamOS plus Linux system requirements, along with Steam-specific features such as Steam Cloud and Family Sharing. Those details describe the Steam release and should not be used as Nintendo hardware specifications.
What console TBA means
Console TBA leaves the console destination unspecified. It does not select Switch over another platform or attach a release date. Treat wishlists, controller layouts, and player expectations as separate from an NPC Studio platform announcement.
How to check a later update
Open the NPC Studio announcement page, press kit, or FAQ and look for the exact words Nintendo Switch. Then match that announcement to a Nintendo product page for the relevant territory before relying on a date, local price, edition, or hardware feature. Keep Steam news with the PC record because a Steam update alone does not create a Nintendo edition.
