While the Switch version seems unaffected, Amazon US has removed their listing for the Wii U release of Breath of the Wild. Some customers who pre-ordered the game have received emails telling them that it no longer has a release date. This is slightly concerning for anyone looking forward to the Wii U version of Breath of the Wild, but it is probably just a mistake on Amazon’s side. Check your order just to be safe.
