oh man this could be the best legend of zelda game but I'm still thinking, I hope that princess Zelda is not stuck in the castle the whole game, what if princess zelda is only alive in the past?
shes my favorite nintendo character and damn in the last trailer scenes "story scenes" Link doesnt have the sheika slave and he is wearing only the master sword what means = He is in the past with zelda even with zelda in the blue champion outfit it is the past.
The master sword obviously goes to shit in the past because of guardians/ganon and you can see it in the trailer, then zelda defends link and sends him to sleep, place the sword in the lost woods/deku tree. then when the deku tree is talking to link at the start of the trailer we can see the master sword in a good form and link with sword/shield/bow so it means mid/final game.
Zelda playable in the past or atleast a companion at some point after the open your eyes/plateau stuff, dont let her be just a cutscene/final battle like in Twilight please Anouma.
also I truly believe there are going to be only 4 dugeons that are these big beasts (camel, bird, elephant, etc.) the trailer and the calamity ganon map are pretty obvious with it, doesnt mean that we cant have ice caverns, ikana castles, lent of truth dungeon and similar stuff, Im sure that besides the 90+ shrines and the 4 beasts the game will have some mini dugeons like those from majoras/ocarina.
