At the very end of Nintendo's E3 showcase, it was confirmed that The Legend of Zelda: Breath of the Wild is getting a sequel.
Released in March 2017, the original Breath of the Wild launched to critical acclaim and commercial success, and whilst we didn't actually see the title 'The Legend of Zelda: Breath of the Wild 2' pop up onscreen, we did get a message telling us 'The sequel to The Legend of Zelda: Breath of the Wild is now in development.'
Hooray.
