Apple's MacBook Air duo to receive Sandy Bridge and Thunderbolt upgrade in June or July?

We've already seen Intel's 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.
