Nintendo has revealed through their recent financial report (PDF) for the third quarter of their fiscal year that The Legend of Zelda: Breath of the Wild has established itself as the second-best selling Zelda title in the series.
From the report, we can see that the Nintendo Switch version sold 6.7 million units globally, while the Wii U version was previously reported to have passed 1.08 million units. Math would show this puts it at around 7.78 million units total.
This puts it right behind The Legend of Zelda: Twilight Princess which boasts an impression 9 million units in its lifetime. Considering that game was released on both the Nintendo Gamecube and the Nintendo Wii, it's a pretty fascinating contextual comparison.
Time will tell whether Breath of the Wild will be able to ascend to the throne, but it should be noted that the sales for every entry include its ports, like the 3DS version of Ocarina of Time or Twilight Princess HD for the Wii U. It is very likely we will see the same happen to Breath of the Wild on future platforms.
