I'm on the side that we will see a new MacBook Air. They've been working on the M1's successor for a long time and this is about when I'd expect it to be announced. Mac leaks are inconsistent, sometimes we get them and sometimes not.
Maybe speculating is just funI understand conjecture in the months and weeks leading up to WWDC, but in the days and hours beforehand, what's the point? Just wait.
NB - I understand this is not how human brains & excitement work...
