As noted by 9 to 5 Mac stocks of MacBook Pro models are beginning to run low in Apple's brick-and-mortar stores. Several of Apple's location around North America are beginning to show the status "Unavailable" when attempting to reserve models for purchase.
The news comes hot on the heels of reports that stock is beginning to run dry in Apple's third party retailer channel. Last week new dummy SKUs appeared in Best Buy's system, a potential sign of an incoming refresh.
The MacBook Pro was last updated in April 2010.
