Xb1 will likely win November but the BF boost will also likely boost the Ps4 to a close the gap between the two(Ps4 GTAV+TLOU bundle is now number 1 on amazon, hourly while LBP3+Lego also rose to number 17). Sony has the PS experience to start December and if they announce a price drop in that event, or a really big exclusive then no matter what deal Xb1 gets, PS4 will rule December.
