If you are thinking of buying a MacBook Pro next week…hold on for a few days because a refresh could be just a few days away.

The guys from 9to5Mac found that MacBook pro line is heavily constrained with some model nearly out of stock. If you follow Apple products, then you know that this normally means a new product is about to be launched.

Also, new models have appeared in the Apple’s inventory system for the entire range but in the same 13-inch, 15-inch and 17-inch.

The refresh is expected to be a minor one, and not the entirely re-designed version that will possibly come in 2012.
Apple will probably upgrade the Pro line with faster processors, possibly the Bluetooth 4.0 technology that is already present on the iPhone 4S and in the MacBook Air, and maybe will upgrade the USB port to 3.0.

According to the publication the refreshed MacBook Pros could be here as soon as Tuesday.
