The AppleInsider site is reporting that Apple is to release MacBook Airs later this month that will again feature backlit keyboards.

All three iterations of the first-generation of MacBook Airs (Early 2008 to Mid-2009) included backlit keyboards as standard features. The redesigned MacBook Air line which was released last October omitted the technology.

The site claims the reinstated feature will join the string of hardware enhancements planned for the new 11.6- and 13.3-inch notebooks, which are also expected to adopt high-speed Thunderbolt ports, an upgrade to Intel's Sandy Bridge architecture, and possibly high-speed 400MBps flash memory.

AppleInsider further reports that the new Airs will make their debut during the week of July 21st, making the white 13.3-inch MacBook the only notebook from Apple to lack keyboard backlights.
