Who will hit 20m in the US first? PS4 Vs. XB1 Vs. 3DS

[PenguinZ]

I'm going to go for the 3ds overall... Simply because of the lead it has.

 

As for PS4 vs. XB1.... Microsoft has better selling exclusives that cater towards the US market. Sony has no answer for Halo in the US market. So I will actually give the edge to Xbox One reaching 20m first in the US market, because Microsoft's exclusives outsell Playstation exclusives in the US.. 

I'll add that titles like CoD also favor the Xbox One in the US market..
