Since then, Intel has announced Skylake chips appropriate for the 13-inch MacBook Pro in September and 15-inch MacBook Pro earlier this week. The Early 2015 13-inch MacBook Pro is based on Intel's newer Broadwell chip architecture, while the 15-inch model still has older Haswell architecture. Both notebooks received Force Touch trackpads, faster flash storage, longer battery life, and improved graphics. For this reason, the 13-inch model is classified as Early 2015, and the 15-inch model is Mid 2015. Last year, Apple refreshed the 13-inch MacBook Pro in March, but its 15-inch sibling was not updated until May. While that seems questionable, Apple may elect to announce a new 15-inch MacBook Pro at WWDC and begin shipping the notebook later in the year. The larger 15-inch MacBook Pro may not be launched until after WWDC, however, as the third quarter translates to between July and September. Smaller updates could also be announced at any time via press release.

If accurate, new 12-inch MacBook and 13-inch MacBook Pro models could debut at Apple's rumored March media event, alongside the new 4-inch iPhone, iPad Air 3, and Apple Watch updates, or at WWDC, likely scheduled for mid-June. The company's manufacturing partners are expected to start producing new 12-inch MacBook and 13-inch MacBook Pro models around late March or early April, followed by 15-inch MacBook Pro models in the third quarter, according to the sometimes-reliable Taiwanese website DigiTimes.

Apple is expected to refresh its MacBook lineup in 2016 with Intel's faster Skylake processors and Thunderbolt 3 with USB-C, and supply chain sources now indicate the updated notebooks may see a staggered launch throughout the year.
