my favourite 3d zelda game was twilight princess, sure it's got a dumb gimmick (but don't worry, this one will have it too, i'd vote between drawing your map on the pad,using the pad as a shield or something that involve controlling two character at once so that one can be on the pad and the other on the screen or even all 3 all at once) and it had padding like those dumb section with the light tears...
but it got place that were fun to dick around like that sand ruin and the castle with the yeti family in it,none of that power ranger themed temple's shit, it got items that were fun to use like the spinning top and the ball & chain, the bosses even had their own music theme... it had a lot of personality and i think that should be the basis
honestly i don't know how they could fix zelda, the combat is boring but there is no way to fix it other than making it more similiar to other action games (go with a faster pace like with platinum games? copy dark souls?) but worst of all, it's all the thing that have been regurgitated over and over and over to the point they've become trope of the games, the hookshot! the bombs! (that always go inside some boss mouth) the boomerang! all this shit is boring as fuck but they are the element that make a zelda game... open world isn't certainly the answer, open world is
