Silence on The Legend of Zelda: Breath of the Wild 2 has dropped for a while now, also considering that - currently - it is not even confirmed what the game will be called. However, we do know that a direct sequel is on the way, and that this will receive new information soon. As confirmed during the Nintendo Direct of February 17th in fact, not long, soon Nintendo will reveal further official information on the production.
However, we do not currently have more precise details, but we are sure that by now the Japanese software house will be able to communicate a launch window (and full name) of The Legend of Zelda: Breath of the Wild 2.
