No 32GB options on any of the models announced today is a shame. Or not I guess as it means I won't be buying anything today M1 looks impressive, hopefully it scales as well to higher TDPs. Pretty much what I expected today with all the low power models getting updated. With no fan I expect the Air will throttle the CPU quickly when using the high performance cores. Calling it an "8-core CPU" is a little cheeky IMHO…
Yeah one possible explanation I can think of is that they're not 100% confident in how rollout will go, and they want to avoid the situation where people in the wild are showing off their "brand new macs" which are still going through teething issues. There's less chance of souring the brand impression of M1 if they blend into the product line better.
Alternatively, maybe they want to sell twice to early adopters: once for the new chip, and again in 12-18 months when they release a refreshed design.
