Sony is very rapidly picking up the pace with their endeavors on PC! It started out pretty slow the first couple of years, then suddenly they're starting to fire on all cylinders. You had:
2020
Horizon: Zero Dawn Complete Edition
2021
Days Gone
Predator: Hunting Grounds
2022
God of War
Spider-Man Remastered
Uncharted: Legacy of Thieves Collection
Spider-Man: Miles Morales
With that kind of momentum, I wouldn't be surprised if 2023 looks more like
The Last of Us Part I
The Last of Us Part II
The Last of Us multiplayer game
Returnal
Sackboy: A Big Adventure
Ghost of Tsushima
Demon's Souls
Then just as a bonus throw in possibility: Dreams
Once 2024 rolls around, that's when I would be expecting the heavily rumored launcher would drop as well as more recent titles such as
Horizon: Forbidden West
Gran Turismo 7
God of War: Ragnarok
Once the back catalog has been ported to PC, I have no idea what could possibly happen lol. Would Sony just allow super long dry spells of first party releases on PC or would they eventually allow day in date releases? Nixxes so far has shown to be extremely competent in porting to PC. Not even a year and a half after acquisition and they will have ported both Spider-Man games!
