TLOU 2 was "remastered" earlier this year for PS5, so that's probably going to come to PC earlier next year.
PS5 Stuff that has yet to make it to PC:
Astro Bot
The Last of Us Part II Remastered
Rise of the Ronin
Stellar Blade (soon)
Spider-Man 2
Gran Turismo 7
Astro's Playroom
Demon's Souls
I'm certain Astro's Playroom won't make it. Demon's Souls, TLOU 2, Spider-Man 2 will probably be the slate for next year.
PS4 games going backwards:
Concrete Genie
MediEvil
Shadow of the Colossus
Knack 2 + 1
Gravity Rush 2 + 1
The Last Guardian
Ratchet and Clank (2016)
The Order 1886
God of War III Remastered
Uncharted 1-3
Bloodborne
Killzone: Shadow Fall
I removed most of the really obvious stuff that 100% will never make it (like the pile of MLB The Shows). Also removed Dreams since that is dead.
A lot of the PS4 stuff seems very unlikely. Between being a failure or being too old.
The Order absolutely could just be ported over, since it's still a stunner, but it wasn't critically or commercially acclaimed.
I could see Sony pushing for full Uncharted, God of War remakes the same way that we saw TLOU 1 remake. It'd be a lot of work, but I think they'd find that worth more than making a Knack remaster...
I feel like there's 1 game in particular on that PS4 list that sticks out, that was successful and modern enough to be worth a PC port.
