I have seen a few die hard pcmr mates are on the consoles now and they seem to have switched during the ps4 era. With the state of the GPU prices I doubt they will return while its this poor.
Many are still converting as we speak and you are right when the ps4 era consoles came out it was a big change in the console market for people that had no interest in them before because they were playing games the pc was and games that were exclusives and looked just as good on their tvs as they did on their computers and acceptable performance. Same happened to me the first time in decades I have a console (ps4 pro) sat under the tv because it does what I need for the odd times I just want to kick back and play something, also have pcs and 2 gaming laptops but I spend more time on them doing work or creative stuff than gaming these days and when I do have the time to game I find it is just to get it out of my system or I'm bored for a while and need to do something and the console is the perfect device for it now.
Once they bring out ps6 and if they ever bring out a ps5 pro that should be about double the performance of the ps5 as they did with ps4 to ps4 pro, most people won't care about pc gaming and I think most of the diehards on pc either have a huge game collection or have a certain game like ms flight sim they want to do on a pc and even that is now on XBOX and the excuses are getting less and less reasons not to get a console with the pc market a mess and a monopoly clearly now (Nvidia and AMD are both in it together as we have seen now), I don't know time will tell and streaming services I really dislike for gaming but even they are now taking off too and not really something I'm interested in as I'm someone that likes to collect media or own what I buy and can have access to it all the time and streaming services as we know love to remove stuff from time to time or their licences expire etc etc.
The gaming future is becoming very interesting and I smell changes are coming for many people and the streaming side of things may even kill off consoles in time and sony and microsoft would love that too and that way sell you a dumb box or the tv built in app to play and same on tablets/mobiles and any pc hardware windows/mac/linux etc. Nvidia is basically doing that now and also by raising the prices of their hardware almost forcing people to use their streaming service if they want to play pc versions of the games, it's all clever what is going on and would not be surprised if AMD started to offer such streaming gaming services too in the future.
Time will tell and with faster and faster internet connections and connected anywhere these days too, these services may end up killing off all gaming hardware and services like netflix etc have killed off recording devices for tv watching and people are also fed up of the size of the software these days and the hardware requirements, this will save many people large downloads and never ending updates and it should just work and work to a level people will not be bothered about owning gaming hardware anymore and also some don't like the idea of media in their homes like dvd/cd/bluray etc.. Not really a future I like the look off but by then who knows I do use Spotify and audio services these days and I do collect cds and highres audio files, but the convenience sometimes wins and the ability to take say your tablet in kitchen and play some music stored or streamed.
