God of War 2 won't be a launch title anyway, not even a 2nd year title, HZD has a chance though and Sony will need at least one or two exclusives to entice people over.
Now that Polyphony has already a lot of car models remade in GTS, new Gran Turismo is likely for launch window to promote online multiplayer and PSVR2. Maybe some exclusive from a third party developer. Then there will probably be some smaller games (like Resogun/Knack with PS4).
So fall 2020 and 2021 could look something like this:
- Gran Turismo 7 (launch, for the reasons stated aboce)
- Wild (launch, that's why they're quiet about it, right..?)
- Japan Studio game (launch, surprise us with something not named Knack)
- New Ratchet & Clank (spring 2021, remake was a success so...)
- Horizon Zero Dawn 2 (spring 2021)
- Some 3rd party collaboration (fall 2021, FromSoftware?)
- PlayLink / VR games etc.
... for giggles yet another Accurate Prediction list:
2022:
- God of War 2 (spring)
- Marvel's Spider-Man 2 (fall)
- Housemarque's new game
- PixelOpus new game
2023:
- Media Molecule's new game (spring)
- Days Gone 2 (summer)
- Death Stranding 2 (fall)
2024:
- Guerrilla Games multiplayer (spring)
- Ghost of Tsushima 2 (spring)
- Naughty Dog's new IP (fall)
Plans can change though...
