No. Fire Emblem Awakening hasn't hit 1 million either. It's just under that.
The last FE title for the DS in Japan (FE12) actually did worse than AW4 in terms of sales. It only sold about 270k, whereas AW4 has totaled about 400k in its lifetime. That's probably the reason why FE12 never got localized to English. AW4 is in fact the second-highest selling AW next to AW1.
Hilarious, considering that Japan never even got Days of Ruin.
