Obv the year will end much differently, Xbox has a very slow start of the year with excellent games coming at the end of the year with Sea of Thieves, Cuphead, Cities Skylines, Path of Exile and Crackdown 3 & State of Decay 2 being console sellers.
Now we can pretty much assume Forza Motorsport 7 will also arrive this year and show some real 4k splender on the Scorpio since its a game that has had no problems on 1080p/60FPS on the console and I can confirm the engine is a true champ on PC.
Also the Switch with Mario, Zelda and Splatoon and a much better naming & system overall then the Wii-U will leave its oler brother way behind.
The PS4 on the other hand has started the year in LEGENDARY fashion with Nioh, Yakuza, Horizon, Persona, Nier and more its just an early year to remember.
Obv. Ps4 will remain the king for this entire generation but I do believe the Xbox One will come closer then before and the Switch will be a competitor and before the generation is done the Xbox One will outsell the PS4 in NA and the Switch will outsell the PS4 in Japan, I think.
