It was launched in 2013 for $130 and was cut down in August 2015 to $100 and the price was again reduced to $80 that took effect in May 2016 could be the reason of this impressive sales increase according to Nintendo. They also cited the "Excitement for the Pokemon brand".

It plays almost the complete library of Nintendo 3DS games without the 3D effect. Blue, Sea Green, Red, Crystal Blue, Crystal Red and more are the available colors for the 2DS console in the US.
