From what I can tell, you can only access a map through using the + button. I've not seen any footage on the HUD that displays a mini-map. And I'm not sure about the rest of you, but personally... I enjoy this. Even in Twilight Princess if you decide to neglect using a mini-map, you've still got that annoying thing that has the number 2 and a right arrow, always letting you know "Yes , you could be using a mini-map right now." It's just taking up space. I kinda hope there's no mini-map in this game and that the map is entirely optional. Would add to the feeling of exploration.
