Do you think Rhythm Heaven is the finale? Or will Nintendo continue to drop some small release for NS1 every so-often?

NOTE: I am not counting ports/remakes/remasters here. Only games such as Metroid Prime 4: Beyond, Tomodachi Life: Living the Dream, and Rhythm Heaven Groove; not something like Luigi’s Mansion 2 HD.

I think we're heading into late 3DS territory where it's ports/remasters/remakes. So, I voted no more are left after Rhythm Heaven. Though it's still probable one more is on the way.

None, outside what is announced. all S2 moving forward.

I am gonna bet on Nintendogs 2 (Nintenpets) next year

I'm betting we get at least some Switch 1 support into next year. Too many people have that console to completely neglect it.

There's a good chance there's 1-2 small original releases left I'd say. Warioware Gold was the last original one on the 3DS if I remember right and that came out close to 1.5 years after the Switch came out and unlike that situation the Switch 2 is backwards compatible with the Switch so no harm in a small game not really taking advantage of the Switch 2's much greater capabilities releasing on the Switch 1 as well to take advantage of its install base since Switch 2 owners can buy it too. That install base is shrinking fast now though so the first half of next year is the latest it should get anything.

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.

I can see one or two smaller releases happening, just cos there's still well over 100 million Switch 1 owners who haven't upgraded yet. It won't be anything big though, just the sort of stuff 3DS saw post-Switch.

I am skeptical that would come to Switch, and if it did it would be cross-gen. Switch doesn't have a microphone, and I think Nintendo wouldn't release a Nintendogs that had no version to use a mic in.
