The Legend of Zelda: Ocarina of Time 3D Passes 3 Million Sales
89 weeks after launch, the week ending February 23, 2013, Ocarina of Time 3D rolled past the 3 million mark. It is the fourth 3-million-seller on 3DS, after Super Mario 3D Land, Mario Kart 7, and New Super Mario Bros 2.
Although 3 million is the "low end" of sales for the Zelda series, Ocarina 3D is the first remake in the franchise to reach the milestone, coming out ahead of A Link to the Past/Four Swords for GBA (2.70 million) and Link's Awakening DX for GBC (2.22 million).
Ocarina of Time 3D seems to be selling a solid 5k or so each week, so it's feasible that it could reach 3.2 million or higher over time, but don't get your hopes up for 4. It is actually ahead of Spirit Tracks for the DS in aligned sales, so I'd say 3.2 million is very possible.
