It is already being touted that Apple's next MacBook Pro, an ultra-thin 15-incher, will come with a Retina display and could even be announced at WWDC in the middle of June. Now, reports suggest that the high pixels per inch screen technology will also be adopted for the next wave of MacBook Airs.

Sources in the supply chain have told 9to5Mac that the overall design aesthetic of the 2012 MacBook Air family refresh will be largely unchanged, but they will each sport the Retina display technology used on the iPhone 4, 4S and new iPad.

They claim that there will be new 11.6 and 13.3-inch versions, which will be powered by Intel Ivy Bridge processors and faster graphics chips than before. The battery demands will be higher with the Retina displays, they say, so that issue will also be addressed.

There's no word as to whether Apple will be looking to add USB 3 connectivity to the new MacBook Air, something believed to be being considered for the MacBook Pro. However, the same sources say that higher resolution iMac display panels have been turning up in the supply chain. There's no word on what those resolutions are, but the current 21-inch model is 1920 x 1080, while the 27-incher offers a maximum resolution of 2560 x 1440.

It is not expected that the new iMacs or MacBook Airs will be unveiled at WWDC. Apple will most likely stick to revealing the new MacBook Pro and is expected to announce iOS 6.

Do you think a Retina display will elevate the MacBook Airs over their Ultrabook rivals? Let us know in the comments below...
