So to me this name change seems logical as Sony ports more games to PC. Like what Jim Ryan said "The cost of making games goes up with each cycle, as the calibre of the IP has improved". Clearly that means with dev costs going up one platform alone cannot support the costs.
To me this doesn't seem like a trail case anymore, Sony most likely sees how easy and most likely cheap it is to port their games to the PC now that both PS4 and PS5 have been pretty much PC's with a custom OS, unlike with the PS1-3 So once again like Jim Ryan said "“Also, our ease of making it available to non-console owners has grown. So it’s a fairly straightforward decision for us to make.”.
That doesnt sound to me like someone or a company that only plans on releasing very old games to me. Imo i see Sony turning PSNow into both their gamepass and Store front on PC. I dont think it will take as long for say GoW 2 to be ported as the first one (Already rumors its being ported by the same devs doing GoW PC port), same with Horizon 2. Imo when Ryan is on about dev costs going up he clearly isnt talking about PS4 dev costs, even if it is PS4 games being ported for now along with the first PS5 game being Sack boy.
To me it all just seems very much like when MS was first stepping back into the PC space. The will be some old games at first to build the audience, they will start putting them games on PSNow (Maybe even rebrand PSNow) for PC users to download instead of Stream as part of their subscription (Like PS4 and PS5 users can do). 3rd party games who already have games on PC and PSNow will most likely allow to download them games too. At Sony's output pace if they keep going as they are i see them Gaining ground on their new IP's and Sequels within 2-3 years. People who own Playstation consoles will still own them just like people who own Xbox Consoles still own them. Xbox sales are up so far this gen compared to last gen when they had exclusives before they started porting their games day and date with PC. So it seems the benefits far outweigh the negatives and i think Sony now knows this just as MS does.
