Videogameszone made their list of wishes for the new Wii Zelda. They like to have 40 hours of play, numerous sidequest and a more open world. Also the dungeon items should not always be the key for beating the final bosses.
A Legend of Zelda fan has been modding various aspects of Ocarina of Time into The Wind Waker over the last few years. They recently gave a big update on the project and it looks great.
Screen Rant, "The return of one controversial character could have an incredible effect on The Legend of Zelda, prompting the introduction of new features."
Honestly I really changed my mind on Fi with the remaster because they didn't make her interrupt your gameplay every 5 seconds, that drastically changed my views on her
Technically she's in ToTK but obviously can't take any other form than the sword she was made into. Also the companion feature has been done plenty of times in Zelda, I don't think it'll add anything new. If anything should be brought back it should be the Minish.
Matt from We Game Daily writes "The Legend of Zelda series has gone in a different direction. One which, try as I have, I just can’t get on board with. Here is why I think Zelda should return to its 3D roots."
Amen! A good, tight, Zelda game with a focus on dungeons and puzzles. Let people have the new style Zelda if you gotta, but let us have the OoT style games too. That's not without precedent either, the handheld 2D Zelda's in the style of A Link to the Past etc have coexisted alongside the 3D Zelda's before
Wind Waker had a perfect balance of open world and a cool, well hand-crafted design. Maybe try to keep the open world but put in effort to make more memorable story driven quests and locations.
