All guesses. Seems to make sense, but we don't know yet what the beta of 18.1 will bring. It wouldn't be beyond possibility that 18.1 keeps being tested well beyond October, and no would be seeing 18.1 in the public form for a while. Adding AI to 18.1 beta forces Apple to have the parts of AI that are available to be very solid before full release. Rather interesting place to put themselves. May see some .01 and beyond public releases before 18.1 comes.Exactly this.
Both devices currently can go on either 18.0 or 18.1 beta. So, clearly intention is it’ll get both.
I’m dead certain that all devices will get 18.1 beta once 18.0 releases, and then will get 18.1 when released publicly.
I’m happy to be proven wrong, later this year, though.
