Looks like the rest of the year is going to playstation, which isn't a huge upset, in my country (The Netherlands) the Fifa bundles where selling well for both Playstation and Xbox One but people don't seem to be buying the gears of war or battlefield bundle.
They are both just quite expensive in comparison the Fifa 17+XBox one S 500Gb was 277,- and many offered a copy of mafia or gears of war 4 if you paid 319,-.
When the Gears of war 1TB or Battlefield 1TB costs 349,- here, and people also find the battlefield 1 bundle "ugly" since its military green :P
I think the same is kind of happening in the US, last month there where a lot of deals and all the good bundles did really well and the bundles on sale right now are just not as attractive so most people are either waiting for a better deal or already bought one.
And since the better deals will proberbly not arrive this month, PS4 will take the rest of the year, the PS4 Pro pre orders have been doing well for many weeks and that increase cannot be stopped by any stretch of the imagination.
