Considering how the 14" and 16" Pros are virtually identical aside from size and battery life, I think we can safely say this will have the exact same specs and options as the current Air.No 3nm, pro motion, no sale
What I would like to see is the old design 13" Pro get replaced with something closer to the weight of an Air, a base M2/3/whenever they do this with active cooling and a ProMotion, HDR, mini LED, full 2x retina display. The display on the 14" Pro nudged it over the edge for me, but I think I'd be ok with a base M-series SoC with the same quality display.
