The new MacBook Air isn’t even close to a year old. But already Apple is looking to upgrade its super-slim laptops, with new models rumoured for release in June or July.

The news comes from Taiwanese component suppliers, speaking with Digitimes. Sources close to companies who build and assemble the MacBook Air say updated versions of both the 11.6 and 13.3-inch machines are getting Intel’s new Sandy Bridge chips and Apple’s much-trumpeted Thunderbolt tech.

Last month, Apple revealed new models of the iMac which pack the same tech, while updated MacBook Pros, released in February, also tout the same specced up archictecture and USB-bashing connectivity.

Word is that shipments of the new Apple devices will start at the end of the month, with Cupertino set to reveal all in June or July. With its Worldwide Developer Conference kicking off in the first week of June, don’t be surprised to see them there first.
