Buried in today's news about the new MacBook Pro was a short blurb on a new 13-inch MacBook: The 12-inch MacBook will also be joined by a 13-inch MacBook, according to Kuo. The analyst believes that Apple will move forward with all three MacBook lines this year, with the MacBook Pro occupying the high-end slot, the MacBook will replace the Air as the medium-level model and the MacBook Air will serve as an entry-level model with comparatively low prices. It was mentioned in this Apple Insider article that the 13-inch MacBook is expected to launch in the third quarter of 2016. The third quarter of Apple's fiscal year ends around the week of June 20th. With the WWDC keynote scheduled for June 13th, it's looking likely that Apple will announce the 13-inch MacBook at the conference, with a release during the days following. Alternatively, it could launch during the third quarter of the calendar year, which would place launch between beginning of June and beginning of September. It's curious that Apple could release a MacBook that is only one-inch larger than their current offering. However, though one-inch might seem small on paper, it does have a perceptible impact on the size of the content. If these rumours are indeed accurate (Kuo does have an excellent track record), I'd expect the 13-inch MacBook to have enhanced capabilities, including: Higher resolution, 2560-by-1600 display; the same as the 13-inch MacBook Pro, 2x USB-C, 1 audio port; addressing the complaints due to the 12" MacBook's single port, Larger battery and potentially longer battery life, Improved CPU/GPU performance, with less throttling due to larger chases allowing for greater heat dispersal, Thunderbolt 3, since they'll be room for a larger motherboard, and hence the chip(s) needed for Thunderbolt, 60 Hz 4k video output support (via Thunderbolt 3) So I'd hold off on purchasing a MacBook until after WWDC if you were looking to purchase the 12-inch model.
