Apple announced yesterday that the new MacBook Pro models were shipping immediately, recent orders show shipping estimates have rapidly increased. Early estimates were 5-7 business days and then increased to 7-10 business days. Today they are estimating shipping time from 2-3 weeks.
This estimate seems to apply to all configurations and customizations on the new Retina MacBook Pro. Currently there is no in-store pickup options on the new MacBook Pros. Apple’s non-Retina MacBook Pro and MacBook Air models are in stock and ready for immediate shipment.
