I'm going with July 2027 that we'll still see new games release on Switch from Nintendo. More specifically I think this fiscal year ending March 2027 will be the last fiscal year we get new Switch games. After that I expect only re-releases, remasters and remakes (not counting NSO games of course). Nintendo already said they're still developing Switch games, and I'm certain games that target a more casual audience would still release for Switch. Also, if I were to guess I think Nintendo would stop releasing games altogether on Switch by March 2028 excluding NSO games.
Unlike Sony and Microsoft once the Switch 2 released Nintendo's biggest games/IP only released on Switch 2 with no Switch release. Metroid Prime 4 and Pokemon are exemptions since they already announced them for Switch before the Switch 2 was even announced. So I'm expecting no big IP will be on Switch going forward unless it's a re-release of some kind.
