PS4 will win July by a normal margin.
PS4 will win August by a smaller margin.
PS4 will win September by a huge margin.
XBO will win October by a huge margin.
We will see the rest.
PS4 will win July by a smaller margin than June
Xb1 will win August by a small margin
Ps4 will win September by a normal margin
Xb1 will win October by a decent margin
I doubt PS4 will win by a "normal" margin, i believe will be much higer than June and even than March. Last year PS4 - XBO gap was over 250k, i think we will see probabily >150k gap this time.
XBO over 250k, PS4 over 400k.
And for October, PS4 will have a decent dropped, more than 250k but less than 300k, and XBO a nice jump... i believe One will be over 400k in October.
The 360 has sold 528k with Halo 3 in September 2007, so, i think is not crazy 400k for XBO with Halo 5.
