Why does everyone here think that commenting on Apple's traditional release schedules is in some way relevant?
It's not.
With Mx chips, it's a whole new ballgame - everything that came before (with Intel chips) is irrelevant. And since the introduction of the M1 everything has been hugely disrupted by the pandemic and supply chain tieups. (I'd argue that getting caught with their pants down by TSMC's screwup on N3B was likely not entirely just due to those two causes, but we'll never know.)
So we literally have NO USEFUL DATA AT ALL about what Apple wanted, or intends in the future.
If I had to bet, I would bet that they do intend to iterate on all the chips in the lineup every year, for as long as they can sustain that for the iphone. After all, once you have new CPU/GPU/NPU/AMX/ISP/etc. designs, you can take it easy on the rest of the design if you need to, reusing a lot of the uncore work from the last year, and still get a decent bump. That means new Pros and Maxes every year along with the base Mx models. It's possible that there could be enough additional complexity in multichip packaging (right now, only the Ultra, using InFO) that that might sometimes lag, and that might also apply to some future chiplet-based design going into the hypothetical Mac Pro, should they go in that direction.
An 18-month cycle is also plausible, but I really doubt it. They do seem to like annual cycles, and if they want to retain an image of leadership in the industry, that's going to be difficult.
