Prediction: PS4 will outsell the entire Nintendo family (3DS, Wii U, NX) by March 2018

[Esiar]

I think there's too many factors to say what will happen. Like how well Nintendo supports the 3DS, and how well the NX does. It's impossible to predict how well it will do because we don't know the specs, games, or even the concept of it, and even if we did, predictions of consoles can be way off regardless of what we know about it. The Wii U is an example of that.
