What I loved about Breath of the Wild was the big wide open world to explore. Exploration is my favourite element of Zelda games and that was like the whole point of that game.
One thing I really did not like about Skyward Sword was how the world was broken up into chunks. If you're going to do that you might as well have separate levels like I'm playing Mario Galaxy.
So those elements seem completely contradictory. How do you have the exploration gameplay of Breath of the Wild if you're using Skyward Sword's bite size chunks? I'm still excited about Breath of the Wild 2 but this is the first thing announced about it that makes me slightly concerned.
Skyward Sword is pretty crappy in a lot of ways and Nintendo has incredibly poor self-awareness if they're going to mine it for ideas. If Fi showed up in that trailer it would have blown up the internet, in the bad way.
