Apple has started to curb the amount of MacBook Pro laptops that it currently has in stores with many nearly out of stock, which nearly always indicated that a refresh of some kind might well be immanent. So if you are thinking of purchasing a new MacBook Pro it might be worth holding fire for just a little while longer.
Other indication that suggest a refresh is immanent is that new references for all MacBook Pro models have appeared in Apple’s inventory system for the 13 inch, 15 inch, and 17 inch screen sizes.
The references seem to suggest that Apple will continue to supply 2 x 13 inch models, 2 x 15 inch models, and 1 x 17 inch model of MacBook Pro. But rather than a huge overhall the expected changes are thought to be fairly small and only upgrades to their processors and the Bluetooth 4.0 technology. Which Apple has started shipping in their new model MacBook Air systems.
