So, PS4 is killing it on Amazon, but the XBO is killing it on Gamestop (mainly due to people picking up the still available $249 bundles.) They're definitely going to do some cancelling out of each other. While I have changed my mind and think XBO will take Oct, I think it won't be any larger than Sept, probably a smaller gap. Nov, however, is easily going to the PS4 by at least 150K-200K, maybe more, basically negating any gains the XBO made the past 4 months.
