It is all about price and exclusives. Some do not want to spend the extra money on a higher performing PC and at that point, you may as well go console. Why would anyone that wants to play God of War 5, Horizon 2, Zelda, Xenoblade, Death Stranding, ghost of tsushima, etc sink the money on a PC when their PS5/Nintendo console can play those same games anyway?
There are some enthusiasts that will, but most will not. They want their one or two consoles to play their exclusive and multiplat games on and that is it. It really is that simple.
