Assuming I'm not twisting things, the game will allow you to do dungeons in any order through "item rentals". I'm not sure how I feel about this. I like the idea of non linear dungeons but the whole "rent items to beat a dungeon" seems a bit iffy to me. Te me, one of the more "magical" parts of any Zelda game was opening up the big chest and getting that new piece of kit. Having it all laid out for me in a rental takes a lot of that away, even if you do end up picking the item up eventually in its respective dungeon. Its kind of like the D3 Auction house, getting rare drops just isn't the same when you can just as easily pick them up off the store shelf.
