Take your time Apple. It's not like anyone's expecting you to innovate on your Mac line a little![]()
MCK said the 14.1" would have a mini-LED backlit display and he has subsequently rumored that the production of mini-LED displays is running behind due to COVID-19. This morning it was reported that Apple has invested hundreds of millions at a new facility in Taiwan to build mini-LED (and micro-LED) panels and it could be that this facility will be tasked to make the mini-LED panels for the 14.1" MBP (along with the 16" MBP and 27" iMac Pro refreshes). If that plant is indeed going to be making those panels and it is behind schedule (again, quite possibly due to COVID-19) then that would explain the delay.
I'll bet the 12in Macbook was a manufacturing trial run at making the form factor for an ARM offering.
I long thought this, but now I am thinking the MacBook Air could be the (portable) ARM launch platform. The MBA does not have a fan (A14X will almost certainly not need one), has two TB3/USB-C ports and with an ARM CPU could have multi-day battery life.
