Like every Nintendo fan I am eagerly awaiting the sequel to Zelda Breath Of The Wild and bracing myself for another possible delay. I am certain the game will be great but I also expect it to be broadly similar to the last game. We can see that from the trailers so far released even if its obvious the game has moved well beyond a quick expansion pack style sequel.
Some of Nintendos best games have come from projects that were initially intended only to be an expansion or quick sequel that reuses existing assets. Super Mario Galaxy 2 and Zelda Majoras Mask are some of the best games ever made and theres every reason to hope that the next Breath Of The Wild will be the same.The reason Breath Of The Wild was such a massive hit though much bigger than any previous Zelda is that it was something completely different. It shook up the series in a way probably no other franchise ever has been and I am certain Nintendo will be looking to do the same thing again probably for the next Zelda after which I imagine while be for the Switch 2. My suggestion is that this game should be first person.
Apart from aiming a bow and arrow and the weird Links Crossbow Training the Zelda games have never really experimented with first person. Most of the modern 3D games have an option to look at the world from a first person view but its usually static and rarely used or useful. My suggestion would be to use Metroid Prime as the inspiration and create a new twist on the Zelda formula that way.Metroid and Zelda have always been similar styles of games. The term Metroidvania gets thrown around a lot nowadays implying its something completely different but its really not. Zelda is not quite as restrictive about how and when you can use new weapons and equipment to open new areas but it still works in broadly the same way.
