You keep bringing up the most stupid example ever. Steam Machiness happened many years ago before Proton became what it is and Linux gaming actually became viable. You seem to assume that Valve hasn't learned anything. Turns Valve is able to do fine with a native portable console while Sony is too scared to even try.Yeah but that's all it is, a concept. It only exists in your head. You keep talking about it like it's a real thing.
The thing is, Valve has tried before and failed. I bet Valve doesn't even have the logistics to put enough systems on shelf, let alone outproduce Sony.
Valve can't even bother to make Half Live 3. What makes you guys think they'll just produce a console in enough quantities to compete with Playstation?
I doubt there is much PlayStation can even do at this point and it seems they just have accepted their fate and will exploit the current user base as it shrinks over time.
The best think MS could do to be competitive is to kill Xbox and focus on Windows instead, Xbox died so they were naturally nudged in a more successful direction and are likely to be a lot more competitive going forward. Sony is obviously going to get sued as well by the likes of Epic and MS just like Apple was and publishers will all side against Sony.
