Of course they do. Sometimes products are underpriced compared to what the market values them at. The Wii, DS and Switch come to mind, just like the PS5 in its early days - all of these console were sold out for long stretches of time. However, sometimes products are overpriced and there's of course a point at which more and more consumers won't see a high enough value in a product anymore and thus sales will suffer.
This is only logical. Just ask yourself: Would you buy your next Android or iPhone if it got a 100$ price hike? What about a 250$ price hike? What about a 1,000$ price hike? There will inevitably be a point where you'll go "nope!".
I do expect PS5 sales to decrease because of this and I also expect Switch 2 sales to suffer if / when Nintendo does something similar. Also, a 300$ PS5 or a 200$ Switch 1 would certainly have sold more units.
