To me it's evident, most of it will come from the devs themselves and if Nintendo mandates it for their own catalog. Maybe their biggest games will get improvments but honestly, I'm not expecting anything else appart some games being more stable with their resolutions and FPS since they are uncapped.
Basically, we might get actual Xenoblade trilogy running at the max settings and with stable framerate which will already make the upgrade noticeable.
