Vita will have the highest YOY percentage going into January (due to China release).
PS4 will continue to PS4.
Wii U will get a price cut and see sales around those this year.
3DS will be below last year but continue to be mobile leader and may see a surge when new hardware hits West.
Xbox One will return to presale levels but get another big boost come holidays. Also think that release of Quantum Break will be pushed up to fight lack of big exclusives in the first half of year.
