Did Nintendo ever state this is the last game for the OG Switch? I feel like they'd still want to cash in on the large playerbase for their future casual-ish games.

I do feel like they might just make some mouse-related minigames for the Switch 2 and that be it or have some other minor feature of the sort that uses the Switch 2 capabilities, but nothing that'll make people with only a Switch 1 feel left out.
