Not to be overly pessimistic, but I think it's pretty clear now that this is the last Intel macOS release.
Monterey supports 2013 and newer. Ventura's cutoff is 2017. That's 4 years of models dropped this year. Considering the cylinder Mac Pro an outlier makes it 3 years. Either way, that brings us to 2020 at next WWDC.
Why kill so many capable machines and then not commit to it? The way I see the strategy, Ventura halves the Intel support list, and macOS 14 finishes the job, making it seem more gradual than if 5+ years of models are unsupported all at once. It wouldn't make sense to anger so many people this year for no reason.
And... I wouldn't be sure about Apple Silicon, either. If they do kill Intel in 2023, I'd bet on them taking advantage of this "new normal" product lifespan, and unsupporting M1 in 2024-2025. We can probably expect 4 years going forward.
Really hoping I'm wrong, but cynicism seems to be the right approach to modern Apple. Absolutely fantastic products, undeniably greedy company
