'Mini-LED suppliers and multiple analysts say otherwise.... strongly doubt the existence of a 14", ...
It's schedule for 2H20 or 1H21.
Those dates were probably many grounded in pre-pandemic assumptions. late 1H21 is likely quite early for a 14" follow on (which would be close to a year and shouldn't produce much a "too soon" complaints ) and 2H21 more likely if get another "second wave " event like Nov 2019 - March 2020 later in 2020.
Even then Apple will probably take the 4 port TB 13" model and just move it down to the 2 port TB space. micro-LED aren't going to be low cost so it won't be a solution at the lower end for as about as long as Apple held onto the non-Retina 13" screens ( and fully rolled out the Retina screens across whole lower end line up.)
