This isn't news - this is common sense. If BestBuy has to ship 250k units from a warehouse, they may not be able to do it all in one day. Some people may get it on Friday, some may get it on Monday, and some may get it even later. Also, being so close to the Christmas season, all of the carriers will also be busy with other deliveries, so the may not even be able to pick up the orders even if they are ready to ship.
This applies to any product launch. The logistics are a nightmare. Heck, even Apple cannot deliver all of their preorders on launch day, and they probably have one of the best logistics networks out there.
