Huh, I thought they'd go underground but they went up in the air instead.
The trailer showed some interesting new stuff, but still very little. I was hoping that they'd have something more substantial to show by now, it's been 2 years since the announcement. Lack of a title and an exact release date is also disappointing.
I'm a bit worried about the world being mostly the same. Exploring was the main appeal of Breath of the Wild and this would make it a lot less exciting. On the other hand, they're obviously a very competent team, so I trust them to be aware of this and to make Hyrule feel as fresh as possible.
