"These price increases have multiple intertwining causes, some direct and some less so: inflation, pandemic-era supply crunches, the unpredictable trade policies of the Trump administration, and a gradual shift among console makers away from selling hardware at a loss or breaking even in the hopes that game sales will subsidize the hardware. And you never want to rule out good old shareholder-prioritizing corporate greed.
But one major factor, both in the price increases and in the reduction in drastic “slim”-style redesigns, is technical: the death of Moore’s Law and a noticeable slowdown in the rate at which processors and graphics chips can improve."
Not exactly, but smaller nodes are getting really expensive. So they could make a “slim” version with a lower power unit, but it would likely cost more than the original.
