That can all still make sense with a more rounded naming convention.
2020 13" Air M1
2022 13.6" MBP M2 (what the new Air is)
2021 14" MBP M1x
2021 16" MBP M1x
Which makes way more sense than what they now have, which is a convoluted mess!
We've already made our decision to go light on the new Air at first. The old thing is more than adequate for 90% of users, and it's $200 cheaper.
