Apple Delaying Early Retina MacBook Pro Orders for Some Business Customers
Dear Apple Customer,It is unclear exactly what is triggering the delays in shipping estimates, although all of those who contacted MacRumors about the delay indicated that they had customized the high-end model with 768 GB of solid-state storage but did not upgrade from the stock 2.6 GHz processor.
Thank you for your recent order.

The Retina MacBook Pro has been in high demand since its introduction during the keynote of Apple's Worldwide Developers Conference earlier this month, with shipping estimates slipping to 2-3 weeks within hours of launch before settling at 3-4 weeks a day later. Estimates have remained at that 3-4 week timeframe since that time.
