I don't know if a patch is planned, but I played it on my Switch 2 and there's a massive difference in performance. Particularly the stages where you drive the divine beasts. On Switch they drop down to like 15 fps or something, on Switch 2 it's super smooth and feels like a completely different game. Here's a video.

It'd be nice to get a patch for extra FPS and more enemies on screen for the Switch 2 though!
