Speculation continues to grow surrounding the release of refreshed MacBook models, as both US and UK stock of the Air and Pro devices becomes extremely limited.
First spotted by AppleInsider, multiple online retailers have removed their entire stock of the current MacBook Air device, whilst Amazon reports limited stock of multiple MacBook Pro models, and even the unavailability of others.
Historically, limited supplies of Apple devices have proven an accurate sign that a refresh of the product is likely.
As for a potential debut of these new MacBooks, that could come as soon as next month.
It's all but confirmed that Apple's next MacBook range will feature Intel's next-gen Haswell processor, which is set to debut in June.
Apple's Worldwide Developer Conference takes place soon after, which itself would be the opportune moment for the firm to unveil its latest device.
Whilst this remains nothing more than speculation at this point, all of the signs would certainly indicate Apple will release its latest range of MacBook devices sooner, rather than later.
