DigiTimes reports that Apple has signaled Taiwan-based suppliers that both the MacBook Pro and MacBook Air series will see revisions in June 2013. As noted by our buyers guide, this would put the updates in line within the expected timeframes.
DigiTimes' sources also reveal that the new MacBook Airs won't have any major external design changes, but will feature a "new processor platform":
The paper also reports that Ultrabook manufacturers are concerned that Apple "is likely to reduce the prices for its existing MacBook Airs before the launch of the new models." Such a move, however, would be extremely unusual for Apple. Apple rarely changes the prices of existing models before they are revised. So, we're skeptical about that particular concern. With the iPad 2, Apple has retained an older product and lowered its price to make room for a new product, but that move would also be unusual for Apple's notebook line.The sources pointed out that the MacBook Air for 2013 will feature a new processor platform, but its industrial design will not see any major changes.
Haswell will incorporate CPU performance boosts as well as double the performance of the integrated GPU. This added GPU performance would be helpful if Apple does standardize on Retina Displays across the entire MacBook line in 2013.
