In a report to investors, Kuo, who has in the past proved reliable in predicting Apple's product plans, says he expects minor changes to the MacBook Pro with Retina display and MacBook Air product lines will be a hardware highlight of WWDC 2013.
The analyst notes Apple's 13-inch Retina MacBook Pro will sport a thinner chassis as the company pushes toward a more portable form factor for its smallest high-end offering. In addition, the Pro models are expected to sport an improved FaceTime HD camera, which could move from a current resolution of 720p to 1080p, or "Full HD."
Apple's new Retina MacBook Pro models are expected to feature Intel's latest-generation Haswell processors, which offer more horsepower with lower power consumption, leading to longer battery life.
WWDC 2013 is scheduled to run from June 10 through 14 in San Francisco. Apple recently revealed that it will preview the forthcoming iterations of iOS and OS X at the conference, both of which are likely to be discussed during an opening keynote speech.
