PS4 - 5.0 millions
XOne - 5.1 millions
Switch - 5.3 millions (assuming there is no undershippment throught the year)
3DS - 550K
Edit:Thinking better, all these numbers really depend on what the Switch ends up shaping.I will leave this numbers here, but depending on what happens in the 12th, ill make them higher/lower.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
