The more healthy players in the market the more innovation. If a company isn't selling enough consoles and thus enough software then they will exit the market. I don't think anyone actually wants a market of just sony and nintendo or worse just one company. It will be bad for the consumer in the end.What's the thinking here? Why does it matter to me as a consumer if Sony sell more PS5s than Microsoft sell Xbox Series, or vise-versa.
On the flip side having more companies in the market will breed innovation or advance progress faster . For example if say google came to the market in 2023 with an intel based console that have an intel core cpu with a next gen graphics card from intel (not the generation in line with the 30x0 series but one after that) It of course could offer a much better visual and performance experiance than the current consoles from ms/sony.
We see it with the steam deck happening now. Nintendo claims the switch is half way through its life span. But Valve is producing a handheld that far and away offers a much higher fidelity and performance profile over what the switch can handle. Just having that 4th console maker or 2nd hand held maker if you want to go there opens up a much more competitive market.
