We are talking about people spending $1000-$2000 on a gaming device, they are trying to blur the lines between console and PC without realising why console is so popular in the first place....... cost. As soon as this is over $1000 and no reason to believe that it won't be, then they have lost the majority of buyers. Ease of use is a very small part of why people buy consoles, heck, most people who buy consoles whether for themselves or for their kids have a PC, may not be a gaming PC but they'll own one so they know what a PC is and how to set things up on it.
You mention PS5 Pro, but can you buy a PC for the price of a Pro that can play the same games at the same quality? Not only that, there is a cheaper option... PS5 (which is still selling far better by the way, why? because its cheaper)
This is also why I believe PS6 will be no more than $700 ($600 is my guess), how well do you think XBox will sell if its double the price, regardless of specs?
