We won't ever know, when these decisions were made. But, I do think departure of guy in my avatar, in addition to shuffling of Yoshida to Indie role basically meant leadership were taking a different approach going forward. Shawn Layden was first boss under whose tenure, a PlayStation game hit PC, which was Predator and he did say, they were considering this strategy for Multi-player games but Single-players were being locked into PlayStation. This all changed under Jim Ryan, and more specifically under Hermen Hulst. From, what I have read of his interviews, Hermen is very business oriented guy, repeatedly pointing out a number of times how not making tentpoles cross-gen is "terrible business" and how "they are leaving money off the table" if they don't make certain games cross-gen, or they don't port.
I think both him, Ryan and other men are keeping profitability was at the forefront, and losing sight of the fact, that their business of PlayStation is not as infallible as they perceive it to be. It's greatest strength is quality of first party exclusives, but committing to porting every PS exclusive is diluting one key and perhaps biggest pull towards a PlayStation hardware. Also. what has made it a juggernaut, is that it has been the default platform for everything 3rd party and they enjoy a consistent 30% cut off every sale and MTX. I am amazed, they are willing to gamble all of this to chase $50m per port on PC.
They are trying to emulate Microsoft, but fail to realize, that Microsoft end goal is to not sell 100s of million of Xbox, or to be the major platform holder for 3rd party, so they can enjoy the store benefits. They are moving beyond all of that and basically creating a storefront and service in form of GamePass. Sony, on the other hand, don't have this luxury. Their attempts at both Cloud Gaming and Subscription Service are half-assed and they themselves have said, that they type of games they fund are not sustainable within this model. So, if there's one platform which absolutely needs hardware to survive and thrive, it's PlayStation. But, not only are they losing some juggernaut 3rd parties, they are simultaneously diluting their own IPs by porting them onto PC. It's a baffling strategy, and I can't make any sense of it.
