The US release has sold more than 180k units since its February 4th launch, with around 63k of the total purchased digitally via the Nintendo 3DS eShop. A hardware bundle featuring Awakening debuted alongside the game's North American release as well, so presumably those are also being counted as unit sales for the title.
