As I find out more and more about the game, it seems like it's going to be a lot like the Wind Waker.
First off, it seems like they don't want to use the obligatory formula of dungeons. I've heard multiple Nintendo people say there will be times when the player isn't even sure they're in a dungeon. They don't want to do the whole "first temple forest, second fire, third, water, etc.". Kind of like Wind Waker. Your first dungeon was sort of not even a dungeon. The Forsaken Fortress did have a Dungeon map, but didn't have a Boss battle, nor a new item, nor a heart piece. The first full-on dungeon was more about Fire than anything.
Secondly, the box art most closely resembles Wind Waker too, with the Gold background.
Graphics have a Wind Waker influence, too, but we all know that.
The music. It's said it will have a lot more acoustic folk instruments in the playing, which is sort of similar to Wind Waker. Wind Waker definitely had an interesting soundtrack, like the opening title theme. Fiddle-playing, and it just sounded more Celtic folk-ish, as opposed to the more proper and classical soundtrack in games like Twilight Princess.
I'm expecting a similar Wind Waker experience. I think it should be a better game than Wind Waker as they aren't rushing this one.
Wind Waker was rushed to come out on a release date, and I think the developers didn't get to do everything they wanted to. Wind Waker really lacked on mini-games, and some parts just felt like "...Really?" (Triforce shards). Skyward Sword definitely wasn't rushed, and delayed sometimes.
The developers seem pretty confident with this game. The only thing is that with all the buzz for the Wii U, I don't think this game is going to be a huge sales-win compared to other Zelda titles, only because of the console it's being released on. The Wii is becoming an afterthought.
