I stopped into the Gamestop near my house and talked about numbers with the Manager there, discussing differences in Best Buy/GS performance for the last two months. His store has 40 copies of Destiny for X1 reserved, and 55 for PS4 reserved, with 4 of the white PS4 bundles preordered. He's seen a much higher uptick of kinectless SKU X1s sold for last month, (a much higher percentage than what we saw in our store), but it hasn't been a constant thing, a universal increase in sales every week.
For comparison, the primary store I operate out of has 40 standard(Non limited/ghost) copies of Destiny for PS4 reserved, and 15 for the X1, with 10 White PS4's preordered. It's also one of the closest Best Buys to the Dixieland border, so no sales tax. (Last I checked we had like 40 copies of the MCC reserved, but most of those were done the week of E3.)
