Some important bits from that article:
-Live Service/GaaS titles will come to PS 7 PC Day 1 simultaneous
-Single Player games will have "at least" 1 year buffer between PlayStation and PC ports
So this lets us know that, for starters, TLOU Part 1 for PC isn't coming until September 2023. It also confirms an obvious: the live service/GaaS titles will be Day & Date on PS and PC, which makes sense because you don't want to split the competitive communities (although I think they'll need to offer keyboard & mouse support for those games if they have them on PC, to even out any input advantages between platforms) or dis-incentivize MTX investments on the platform that gets that game later.
The "clarity" on the single-player stuff, though...well I really aren't sure if there's anything new being said here. It does let know that a port of Returnal to PC is probably imminent for Spring 2023. However I still think that's going to be on a case-by-case, and there may be other games that are 2 years or so out between PS and PC. Spiderman 2 will probably be one such game, given the legs for Miles Morales on PS5 (whenever stock wasn't a limiting factor). Probably the same with Wolverine, and probably GOW Ragnarok as well.
Ideally I think they should prioritize PS5 releases first and foremost (which is what they're doing, for the single-player or non live-service games), then depending on the game, a year (or two or three) later port it to PC; if there are any enhancements or extra content planned roll it into the PC release as a single package and offer that content as an upgrade for PS5 owners for $10. Then a year or so after that, put the game in PS+ Extra & Premium, and roll it down to regular PS+ after a few months.
I think if Sony made some smaller, internal AA-style games with older legacy IP, they could've used those to test out something like Day 1 on PC, or Day 1 in PS+, just to see what they could do. If it works, cool. If not, then no need to try it further.
