According to Taiwanese tech-blog Digitimes, we could be seeing a refreshed line of MacBook Airs as soon as June or July.

The site reports that a Taiwan-based Apple supplier will begin shipments of the 11.6 and 13.3-inch MacBook Air models in May, and which will feature intel's Sandy Bridge processor and Thunderbolt ports. This would be in line with previous refreshes of MacBook Pros and iMacs.
