According to two separate reports from Italian websites SlideToMac and iSpazio posted this morning, the next generation of MacBook Pros -- due an update -- is going to be released next week, with shipments to Italian resellers starting in the next few days to ensure a late February launch. MacRumors has now independently confirmed that the new MacBook Pros will be released on Thursday, February 24th.
We've since heard reliable confirmation that this information is accurate and that the expected release date is next Thursday, February 24th. The move would be a bit unusual for Apple to launch new machines on a Thursday. So, if you are about to buy a new MacBook Pro, wait until next week.
This morning, iSpazio also posted the rumored model numbers of the new units (MC720, MC721, MC723, MC724, and MC725) which will likely sport a new design inspired by the MacBook Airs (dubbed by Apple on its website as the "next generation of MacBooks") and the new powerful Sandy Bridge chips.
In the past weeks, rumors of stock running low suggested the MacBook Pro line was going to be updated relatively soon. At this point, it looks like next week we'll be able to get our hands on the new generation of MacBook Pros.
