The Legend of Zelda franchise may be a huge one for Nintendo, but it doesn't really move the needle over in Japan. The game franchise sells decently, but it's rare that a single entry manages to sell a million units. That's what makes this next bit of information so exciting.
The Legend of Zelda: Breath of the Wild is currently sitting at 935,835 units sold. That accounts for 802,811 units on the Switch, and 133,024 units for Wii U. There seems to be little doubt of Breath of the Wild hitting a million units sold in Japan in a matter of a few weeks. Also, keep in mind that this total doesn't include digital sales. For all we know, the game could have hit a million with that data included!
