I'd say the problem is an outdated method of judging a hardware design's "age." Saying the iMac Pro is "neutral" in terms of modern-ness 6 months out from introduction strikes me as particularly nonsensical. Exactly what should have been updated there? I don't see any advance in Intel's relevant line of Xeons in the interim (and AFAIK Xeon development is itself measured in years).

Obviously, the Macbook Air and Mini are extreme (and genuinely embarrassing) examples, but generally speaking a ~1yr update cycle (everything else on that page) seems entirely reasonable, especially given Intel's more, uh, deliberate pace in recent years.

NONE of the systems have been updated in 365 days other than the hideously expensive iMac Pro. None.

And with no announcement at WWDC, odds are we won't see updates til 1st Q 2019. The next big hardware announcement will be the iPhone in the Fall. They won't mix iPhone with Mac.

It's also important to look at the averages for the upgrades. It's not consistent at all, except the MBP. All the other Macs, it's on a whimsical schedule.

And the updates, when they've happened have been poorly thought out. Castrating the mac mini, foolishly recreating the Cube as the new Mac Pro. Adding the touchbar, while removing ports. The list goes on.

Apple has lost their way with the Mac. Clear as day. They're doing great with the iPhone/iOS, but they're only paying lip service to the Mac and macOS.
