That depends on the shipment numbers for black Friday does it not, I think what's likely is that MS has shipped to territories that are less keen on Xbox so there is stock lying idle whereas countries like UK and US would sell through immediately whatever shipment they have. Sony however , by launching in one territory have effectively distributed their shipment much better, and created demand on black Friday due to lapsed worldwide launch.
Basically I think that ms has shipped close to their sellthrough number worldwide and both consoles are selling on par to what the manufacturers can ship, so much hype around this gen and so much profit to be made through eBay and other used game stores, that people will continue snapping them up, up until Christmas. And both manufacturers are likely trying to supply NA as much as possible while the Christmas hype lasts.
Disconnect and self destruct, one bullet a time.
