When do Apple Authorized retailers get refreshed?
Authorized retailers can order the new units from Apple more or less at the same time the Apple Stores get the new stuff. But while Apple Stores get the new stuff out on the sales floor at launch, the other retailers, for whom Apple gear is a small part of their business, may take longer to get the new stuff shipped from Apple, into their inventory systems, go through their internal distribution, and get it on their floors.
