I find it hard to believe that any decent chipset made in the last decade at least cannot support 32gb of ram. I had a reasonably cheap samsung laptop from 2012 that already did. If apple is not doing it, it's not by the lack of choices in the market.

Of course, but it's a tradeoff. These low power low profile Intel CPUs can support more memory, but only DDR4 which is desktop class RAM with more than double the power requirements in use, and four to ten times the power usage in sleep mode.

The logic board would also have the redesigned and bigger for the new chipset, putting pressure on battery space. You see Microsoft making the same choice as Apple with the new Surface laptop.

Fortunately Intel are launching new mobile chips with support for fast, low power LPDDR3E memory over 16GB this year.
