It's looking like Switch will have closed the gap by about 8 and a half million units in 2018, a year where it had a huge holiday but spent January-October on cruise control with no big releases.
If Nintendo get Animal Crossing out this Summer, Pokemon Gen 8 in November, and a hardware revision/price cut or both in around October, I think they should be able to sell significantly more Switch hardware this year than in 2018, while Xbox One will likely be down YOY simply due to its age.
