Basic combat is alright but nothing stellar. Abilities that go beyond that will be of utmost importance in keeping the combat interesting or else it will be a game where you avoid fighting half the time because you've done it so often.
So that's a "wait and see".
With the overworld, we've seen almost nothing that's really interesting or really challenging (like a Far Cry base). That's a big key for an open-world game. On the other side of that coin are instanced dungeons that are really enjoyable to tackle or explore. Have they shown any of that yet?
So that's a major "wait and see".
Things to do outside of combat are also important, along with interesting cities or villages.
"Wait and see".
Honestly, right now, most of the excitement boils down to "it's Zelda!" and "it's open-world!" We really have no idea if the game is anything special or enjoyable until the biggest questions get answered.
