Yes, we all remember the time when apple would change the design of their Macs every year 🙄 don't be dramatic. The new M2 laptops refresh either changed the design (MacBook Air) or kept a design that was just introduced (MBP 14"/16"). This is completely in line with what they've been doing for at least the last two decades.32 inch would have been such a breath of fresh air. But I guess the fear of cannibalizing other product lines is now a thing at Apple. Selling performance these days is a tough cookie when the latest version is just a spec bump and doesn’t look any different from the models it replaces.
Look at the M2 Pro/Max versus the M1. I think this is gonna have some impact on upgrade decisions.
