Breath Of The Wild 2: 7 Bold Predictions From The E3 Trailer
6. What We Have Seen Is At The Beginning Of The Game
The footage we have seen of Breath of the Wild 2 is most likely the beginning of the game.
It is unlikely that we will have a companion in the form of Zelda (or Link, if the idea of playing as Zelda is correct) throughout the game, as a game-long escort mission in an open-world doesn't sound very appealing.
The ending of the trailer concludes with two major events that clearly set in motion the rest of the game, and these are the waking up of the evil-looking corpse in the centre of the room, and Hyrule Castle starting to take off.
If the castle does something like taking off into another world, it would make sense for that to happen in the opening of the game.
