According to "reliable sources," Apple will announce the MacBook Pro (Late 2016) model in the next few days, shipping it and a new MacBook Air before the end of October.
Macotakara's sources claim that a pair of new MacBook Pro models coming, with both the 13-inch and 15-inch models being refreshed. According to the same data sources in the supply chain, the 11-inch MacBook Air will not be renewed, with only the 13-inch MacBook Air seeing an update.
Both Macotakara and AppleInsider are expecting USB-C and Thunderbolt 3 ports. MagSafe 2 is not expected to return to the new MacBook Pro based on the new report, but data on any MacBook Air ports is limited at this time.
Processors expected in a new MacBook Pro aren't clear. It is uncertain if any quad-core Kaby Lake seventh-generation processors are shipping in any volumes, with only dual-core low-power models known to be in the hand of manufacturers at this time, and shipping in computers from other manufacturers.
