So far we've seen:
- Naughty Dog
- Insomniac Games with Nixxes
- Guerilla Games
- Unreal Engine based games (Sony Bend, Housemarque)
- Santa Monica
All seem to have a good/quick pipeline to PC. We have yet to see Sucker Punch, Bluepoint, Team Asobi (their games are so PS focused, I wouldn't be surprised if it never happens), San Diego (surprised MLB hasn't made it to PC), Polyphony.
Media Molecule is another one that probably won't make their game on PC. The rest I think are currently working on Live Services (Firesprite, Firewalk, Haven, London Studio, possibly Valkyrie) and those I would expect day 1 on PC.
Overall it seems like 2/3rds of Sony has a pipeline set up for PC. Hopefully Polyphony joins the list in the next few months with GT7.
Sucker Punch, Bluepoint and San Diego feel pretty surprising at this point. The former are already like 3 years old, and the latter is already releasing on Switch and Xbox, so why not PC?
