Personally I am loving the format of the current switch games, and Nintendo has signaled that they intend to keep making games in this style though not necessarily a sequel.
I would love first and foremost for the story telling to be brought back to the standards of Ocarina of Time, Wind Waker, and Twilight Princess.
Also, to me the best thing in the 3D games has always been the pacing, you have your first initial quest, that leads to Link powering up in a few different ways. Then Link is set on a second quest, becoming more powerful again. Then a twist of some sort, though that's optional. Then finally the climactic battle with the big bad. I would also like to see more of an after story, though it is traditional for that to not be a thing at this point.
As for settings, I would LOVE to see a game set after spirit tracks in New Hyrule in the midst of an industrial revolution, mixed with magic.
How about you, what are your wishlist items for the next/future Zelda games?
I'd like to see a game where you play as Zelda. I remember there being a question if she was the protagonist of BOTW in the first teaser because Link was wearing the hood up.
I know that the "woke" cries would be ridiculous, but I think it'd be neat to have her save Link for once.
