They won't ignore PC completely. It's enough to ignore Steam and do something of their own or work with Epic. Sony should soon be able to show enough figures in terms of sales on Steam, afaik the PC port of HFW was anything but successful and the PSN account strategy doesn't seem to be working as intended. This should also be easier to integrate with Epic, as there is good experience with linking PSN and Epic accounts. afaik this is even a feature of UE to offer cross play.
I don't understand why Sony publishes titles on Steam anyway. Sure, most users, but how is competition supposed to arise when the clear market leader is supported. As far as I'm concerned, they can throw the PC strategy completely in the trash. I'm a console gamer and if PC players want to play Nintendo or Playstation games, they should just buy a console or not. In my opinion, Sony implemented a PC port strategy too early, and Layden's original idea of showing PC players what they're missing out on if they don't buy a console has completely failed or was probably a lie beforehand so as not to upset the fan base. Sony should have learned from MS, whose strategy failed so badly that hardly anyone buys Xbox anymore and they have to port everything to Playstation and Nintendo.
But who knows, if sales of PC ports stagnate or decline, Sony could phase out the strategy by the time the PS6 launches at the latest. A few years ago, the strategy was certainly understandable. But now they are earning extra money through TV shows, accessories like Dualsense Edge and Portal and thanks to Gacha Games from Mihoyo, Sony is making even more money alongside Fortnite, CoD and Apex Legends. They are now investing in cheap projects in China, India, Africa and South Korea, which means surprises like Stellar Blade end up exclusively on PS5. They don't even have to spend a lot of money on time-exclusive deals with Square Enix.
The best thing to do is to scrap the idiotic guidelines for limiting sexual depictions in games and let Nikke be ported to PS5. Sex and violence are and will remain content that sells, even Nintendo has recognized that and is much more relaxed about such games than Sony and now MS. Let's wait and see what the business figures are and who the new CEO will be. Maybe someone will come along with a completely different idea and try to get more variety in the first party catalog. If Sony is smart, they will take the revenue from the PC and invest several hundred million in Mihoyo and Shift Up. If both bring their gacha games consoles exclusively for PS5, all of their gacha games should bring in more revenue for Sony than the PC ports. Gacha games are, in my opinion, the "new" live service games. To this day, I still find it incomprehensible that Sony owns one of the successful mobile games but doesn't think about using the license for consoles. Ideas like porting Playstation brands to mobile should not be a one-way street.
