Nothing.
Nothing really needs to change.
the only thing that could be improved about Zelda was if the games had a built in sensor that detected if people complained about things like the Art or how similar it was to other Zeldas, and then delivered a shock to the person.
I think the Vitality sensor would be and excellent way to implement this.
Just like wit EVERY Zelda game, people are gonna dislike SS when it comes out, then when another Zelda comes out they will instantly hate it and sing the praises of SS.
