PS4 easily. Both will sell very well, but 3DS has not so good system seller for te rest of the year. A Pokemon remake and Smash won't be enough against Destiny, and if they are enough, it still would need to sell an extra 2 million since the PS4 > 3DS so far.
Bet with bluedawgs: I say Switch will outsell PS4 in 2018, he says PS4 will outsell Switch. He's now permabanned, but the bet will remain in my sig.
