We already know that this is (sorta) true of Mario Kart World: it began development as a Switch title, but the developers couldn't execute their vision on that hardware without significant compromises, so they moved development over to the Switch 2.
Wouldn't be surprised if that happened with Bananza too, given that we've had rumors about parts of the Odyssey team working on a 3D Donkey Kong for a number of years now.
We actually may not have seen a single major first party title that began development with the Switch 2 in mind yet. (Obviously Metroid Prime 4 also was originally an OG Switch game, lol.)
