First of all, as far as I'm aware from being on this site for several years and following Gamestop related items closely, BenV is only a store manager level or possibly regional level over stores in an area/city (feel free to correct me if I'm wrong Ben, but I really see no reason why you'd have to have any hint of secrecy to it or "no comment" type responses. that just fuels unnecessary worry). My contacts of that same level are all saying the same things: "Supply related. Preorders sold out and MS hasn't authorized anymore yet, while Sony has allowed us to increase our total."
I'm guessing a big part of it could be that MS is targeting an Xbox One release of one to almost 2 months before PS4. All the retailers I've seen are "predicting" the PS4 release closer to the end of the year/Christmas time frame where as the Xbox One is looking at early November. An extra month's worth of production this early on could easily make a difference between only 10 per store and 30+. All my local stores were maxed out at 10 Xbox One's per store and 20-30 PS4's.
I remember when the Wii and PS3 came out our area had similar limits. Wii had 20 and PS3 had 15 per store in my area.
