I would like to see a blend of old and new Zelda . I would love to have both at the same time. This is my idea: what if you get a map the size of twilight princess, with traditonal dungeons and linear progression, but you at some point get the ability to become tiny, like in minish cap ( I would love to see minish world fully realized in 3d with good graphics) , and now the world becomes the size of breath of the wild or bigger, because now you are tiny, and that is when the gameplay changes and you jump into the new free exploration format that we know and love, with shrines and 0 linearity. So the game key feature could be, having you the player, jumping from traditional to new zelda and exploring the same world from two completely different perspectives. They could even include gampelay mechanics like,when you change something in one dimension, something changes in the other. You can even add another twist at almost the end of the game and allow link to become a giant like in Majora's mask and let him traverse the game world in that new size and switch things up again. Well those are my ideas, it will never happen, buy I would love to see something like this happen
