PlayStation is more successful than ever with Jim Ryan in basically all metrics (the exception is temporally hardware sales due to chips shortages), and there are zero signs of things going worse in the future. In fact everything points to the opposite, PlayStation growing in every single area and market and they are doubling down their investments on every type of game (they already are or plan to invest more than ever before in sequels, new IPs, GaaS, non-GaaS, games for console, PC ports, mobile games, growing manpower of existing internal studios, acquiring studios, increasing investment in 2nd and 3rd party exclusive, investment in supporting indies...)
Regarding BC, or streaming/game sub, they did a big improvement with Jimbo, making PS5 is full BC with PS4 (this decision was made before him) and supporting new platforms, plus are working on improving emulators and making new ones as seen in other thread that shows a job offer to do so, plus a recent emulation related patent that shows PS3 accesories.
They shown their plans until April 2026 (FY2025) and for that year they don't plan day one PC releases and said they don't plan them for PS Studios (next Bungie games will release day one on PC and rival consoles). Sony consoles release typically every 7 years, meaning that if they continue the pattern PS6 would release in 2027, meaning that pretty likely there won't be day one releases in PC at least for this gen.
Regarding PC ports, for them are extra free revenue & profit from games that already completed their sales cycle. Every generation AAA games becomes more and more expensive to make, meaning they need extra revenue sources to keep the wheel spinning. Porting old games to PC gives them more money and their 1st party game sales and console hardware sales & demand continued at historical record levels. PC caused zero issues at least until now.
