About The Legend of Zelda: Breath of the Wild?

Right now, BotW seems huge, different and complicated in comparison to the other LoZ games. I'm very curious about what items will be in the game and how they will be obtained. With a world this big and vast with so much to explore, how will some key items be obtained, because I doubt Nintendo is going to revert back to the same "get the required item for the dungeon in the dungeon", thing. Like, in some gameplay from Kotaku, we saw that to get the paraglider we needed to go to 4 specific temples out of the hundreds in the game beat them all to collect 4 spirit orbs, and THEN return them to the old man you meet in the beginning of the game. do you think it's going to be this hard to obtain all items in the game? If so, how are we going to know about these items or know how to get them? Are certain characters in the game going to give us info, will we have to rely on the community, or are we just f***ed. Please share your opinions and answers below. Thanks!
