Wasn't that clear? The idea that console owners are solely to blame for weak sales makes no sense to me as sales of a product is a result of its qualities in comparison to competing offers. The fact that Sony is making a faster version of PS5 right now proves that Sony also thinks that the h/w has enough of a selling power on its own for that to be feasible.
You think a more expensive console with nVidia hardware, and possibly no BC, would have sold significantly better?
Who knows? We don't have such options so we can't really know that. But consider this: both console platforms are struggling despite having mostly similar s/w on them. In such a scenario if one platform would be providing sizeable advantages over the other in h/w (perf, features) it would probably be struggling less if sold in a similar pricing ranges, don't you think?
This also means that console owners can't really do much on their own as the main selling power for both platforms lie in 3rd party s/w right now. Looking back I do wonder if a console with different h/w would do better now simply because of that being a differentiator between the options - even if it would lack some b/c.
What would an nVidia console have brought and what would the gamer reaction have been? Was that even an option - do nVidia have the slightest interest in consoles when they can sell GPUs at huge margins?
That's where the risk comes in as that option would be more expensive for the console manufacturer - but maybe that additional investment would've lead to better sales now and in the future? Impossible to tell unless someone would opt for that.
edit: If not nVidia, what could AMD have done differently?
Console makers have successfully pushed AMD into adopting "Turing" tech for their next gen console h/w, and I have little doubt that if console makers would want that they could've just as successfully pushed AMD into making faster RT h/w or adding more ML h/w into their respective console designs - something which Sony is apparently doing now with 5Pro anyway. Hell even adding infinity cache on console APUs could've provided some interesting benefits for RT as well.
These new console APUs as they are can barely keep up with running previous gen games at 2x the framerate. It was very obviously a safe bet on part of console makers costs but this safe bet has lead to the decline in sales about twice faster than they'd probably prefer.
What is this alternative console HW you can think of, and its price, and where does the responsibility lie regards AMD and the console companies?
There are a bunch of options outside of AMD but all of them require more investment on part of console makers - which is basically the only reason why AMD has been getting these designs for the last decade. You could use Arm for CPUs, you could ask Intel to make a console APU, you could license GPU IP from Nvidia (they do that these days), you could even do something weird like RISK-V and IMG GPU for example.
The console platform owner is facing the market and hence the scenario where they make less money in favor of the h/w vendor is non existent. I'm not seeing your point , please clarify as this seems too hyptotetical to me
Does making less money for 20 years sounds worse than making more money for 5?
