So the MacBook Air is now at least very unlikely to get an OLED screen, and certainly won't if it is being released before the next MacBook Pro launch.
Apple is very good at positioning its products and will keep clear daylight between the MacBook Pro and the MacBook Air.
But in December 2024, AppleInsider uncovered that the new MacBook Air will of course get the M4 processor — but also a new camera system.
So on the one hand, using the M4 Pro or M4 Max would stop the MacBook Air being the most affordable Mac laptop.
Given Apple's previous use of ultra wide cameras, it's more than reasonable to presume that the new MacBook Air will get Center Stage, too.
