a few things with mobos could be price is kept high as cpus for 2 or maybe 3 generations can be put there menaing no new mboard is needed in 2 to 3 years.
difficult to say if that is sustainable for a mobo manufacturer.
You're not wrong, and that long term stability is one reason I'm willing to swallow the cost of the board. I'm paying now so's I don't have to buy another motherboard and do a full rebuild in 3 years if I want to upgrade the CPU.
However, that doesn't mean that the cost of components or manufacturing has increased... So it still feels like some kind of price fixing. Not sure products are meant to be priced based on a presumed refresh cycle because this encourages planned obsolescence and things being engineered to fail. (And it's not just AM5 motherboards of course, plenty of things are overpriced atm.)
I was debating whether I need pcie 5... probably not, really, I doubt I will ever buy higher than the xx70 graphics card bracket whether it be 4070 or 5070 or even a 6070. But at this point I've spent north of £1500 on this build, and the step from B650 to X670E was "only" about £80 of it. 6% more total cost to never worry about pcie bandwidth for the GPU, I guess sure.
I would on the whole have preferred boards with less m.2 built in, and more generic pcie slots with bifurcation so they run at x8 or x4 etc, depending on what's populated - why not let the user decide to buy a double m.2 riser card if they want one? But nothing in the mainstream seems to be taking that approach, and I need both my kidneys.
