It is obvious yes, PS4 already won, and even with a big Halo 5 boost, it will be too late, the gap already reached 800, you can add 1M to that in 1 year., never Halo 5 will be enough, it will be temporary but too late because the PS4 will be the main console in general mind
Predictions for end of 2014 HW sales:
PS4: 17m XB1: 10m WiiU: 10m Vita: 10m
