The Air/13" MBP are still limited to one external display (two total). That's a bit disappointing. The SOP for many offices these days is two externals, and this locks them out of that market.
I recall this interview with Samsung in which they said they'd be mass-producting 24 GB LPDDR5x RAM stacks* in 2022; 32 GB stacks won't be available until 2024-2025 (
https://www.tomshardware.com/news/amd-and-samsung-webinar-talks-raphael-overclocking-ddr5-future ). Wonder if they're using LPDDR5x in the M2 Air, or if it's just increased-density LPDDR5. I guess we'll find out soon enough....
[*The chips will be 24 Gb; with 8 chips to a stack, this gives 24 GB.]
