There haven’t been any specific rumors, but I wouldn’t discount it. A 28W Ice Lake SKU is out and a 14” Ice Lake laptop with LPDDR4 will make a great replacement for the high-end 13” MBP.
Both releases are constrained by the availability of CPUs. For the updated 13" we'll most likely see Intel Ice Lake CPUs (including all the benefits), but I doubt the 15" would be released with an older chipset – so Apple might be waiting for availability of Ice Lake across the line.I don’t see why they wouldn’t update both 13’’ and 15’’ at the same time to be honest (at least the 4TB port 13’’)
if they do make a 14 inch. i would like to see a decent gpu
