Suppliers are already working on Retina displays for the next MacBook Air. The Wall Street Journal reports suppliers have been mass producing 12-inch Air displays that are of a higher resolution. WSJ claims the suppliers plan to ship a large number of displays in Q2.

The MacBook Air has not been included in the Retina line of devices up to this point. Apple's 11-inch Air has a 1,366x768 display while the 13-inch is 1,440x990. An Air with Retina would have a higher resolution, wider viewing angle, less glare, and deeper blacks.

Since these reports are on the 12-inch MacBook Air, it appears Apple is soon going to have three Air models available at any given time.
