It's been a couple of years since Apple first introduced the unibody MacBook range, and in that timeframe it has delivered a handful of updates to keep their hardware current. But anyone who is familiar with the company's fairly consistent release cycles (yearly for iOS devices, roughly every nine months for Macs, with new designs every two years) will know that a more significant update to their notebook line is just around the corner -- or so say the latest rumors.

According to a couple of alleged Best Buy inventory system screenshots of their Sandy Bridge chipsets to certain companies, with fixed parts arriving in mid-February, so maybe there won't be much of a delay for Apple's MacBook update.
