Sandy Bridge processors and Thunderbolt reinvigorating the MacBook Pro line, so it's only logical for the MacBook Airs to eventually follow suit -- presumably they'll pick up Sandy Bridge's 17W mobile processors to match the current 10W and 17W Core 2 Duos. So when can we expect this to happen? Well, according to DigiTimes' sources within the supply chain, Apple may receive shipment of the refreshed Airs in late May ahead of a June or July launch -- this echoes earlier reports from Apple Insider and CNET that cited the same time frame. Additionally, DigiTimes says Quanta will continue to assemble Apple's ultra-portable laptops, with Simplo Technology and Dynapack supplying the battery packs. As always, we shall remain open-minded about such rumors, but you'll know the real deal as soon as we do within the next couple of months or so.
