Hard to say. Right now, what Mac is really in desperate need of an update?

If they hadn't shipped those Ice Lake MacBooks Air, I think they would've been the perfect candidate for an update. The Mac mini is also fairly old again at this point (one might argue it's because Intel suddenly decided not to do 'B' CPUs any more, but one might also argue it was an unforced error on Apple's part to use a weird special CPU).

My guess is they'll start with a new Air. Maybe they'll bring it back in 12- and 13-inch versions, replacing the 2015 12-inch MacBook and the 2018 Air, finally giving the two a consistent name, and giving them much longer battery life. They might make them fanless, too. That way, they don't have the awkwardness of the Air being faster in some tasks than the Pro.

Then, slowly work your way upwards.
