okay because all u guys dont know i will tell u:
sony ps4 shipments end of june 10.2m
sony ps4 sold through 12th august 10m
sony ps4 shipments end of september 13.5
so after 10.2m shipped ps4, it took sony 1 1/2 month to sold through the same number
my best guess is 13.5m sold through ps4 the week before gtaV/far cry/lpb3 realse
its normal to have 1 1/2 month of sales sitting on shelfs, at distributors and in transit
