Seeing as users are already creating cheats that are almost identical to BOTW, and playing the game myself for 10 hours (ish), it is clear that Nintendo didn't change a thing in the backend of this engine.
It's BOTW with a few new powers, added content, and a coat of paint on old content (No spoiler of course).
Add to the fact that the switch modding scene for BOTW only started a few years after release (explains why the Wii U scene was so much more advanced)
This means, that I'd assume amazing mods we all know and love will be on the game way earlier than during the BOTW lifecycle.
