You reckon the vanilla 14/Max will have ProMotion?
Given our knowledge of some of the announced "upgrade" triggers. (Referring to consumer psychology and the current conditioning from apple)
The 14pro/ max will have the new screen design and bigger sensors/lenses? to hoot. Good !
What remains for the 14 ? Given the alleged absence of a silicon spec bump.
And given that apple has mastered the rationing of those upgrade triggers to dilute the difference between year models.
And knowing how "weak" the mainstream update trigger was for the 12-13 cycle.
ProMotion across the range would only be charitable. The next generation Air may also get it, given that the next generation iPad pros will get Magsafe and won't have to compete with the Air on the sole merit merit of it's display(Taking about the 11', the 12'9 inch has the monopoly on screen size to boast).
But you'll hardly see objective analysis on these kind of threads, people often projecting their own purchasing pattern in conjunction with subjective needs.
And in the end, unless you're on the ground in the manufacturing plant or somewhere inside of the design pipeline, it's all smoke and mirrors.
