Cost to performance ebbs and flows with each console generation, and console generations are getting longer, or perhaps disappearing if Microsoft is to be believed. PC gaming's market share has been steadily rising for over a decade now, to the point where PC versions of some games that used to be console-only releases now outsell their console counterparts. There are a lot of reasons we could guess as to why this is, but I don't think they're wholly two different markets, and I don't think Sony thinks this either, regardless of what they said in court. They're preparing to set up their own PC storefront, probably without anything that will make people want to use it besides exclusives, even though that's failed for everyone else who tried it, but signs are pointing toward them preparing to do it.
