Looks like I'll be using my current MacBook Air until >= October; hopefully Apple will also see fit to update its Thunderbolt Display, which hasn't been refreshed since it was introduced in mid-2011
"According to a new note from reliable Apple analyst Ming-Chi Kuo at KGI Securities and corroborated by our sources, Apple plans to introduce a dramatically overhauled MacBook Pro later this year. Kuo says the device will have a new “thinner and lighter” design with design cues taken from the 12-inch MacBook, as well as Touch ID support and a new OLED display touch bar above the keyboard.Apple prepping thinner MacBook Pros with OLED screen above keyboard, Touch ID for Q4 | 9to5Mac
Kuo’s report explains that the MacBook Pro updates are the “brightest spot for Apple’s 2016 rollouts” and will come to both the 13-inch and 15-inch models sometime during the fourth quarter of this year.
The OLED display touch bar will replace the physical function keys along the top of the keyboard, while the design will adopt new metal injection molded hinges as reported earlier this year. Additionally, the refreshed MacBook Pros are said to feature USB-C support and Thunderbolt 3."
