If we're basing it off of past experience:
FromSoftware, due to exclusives like Demon's Souls, Bloodborne, and Deraciné.
Insomniac, due to exclusives like Ratchet & Clank, Resistance, and Spider-Man.
Ready At Dawn, due to multiple PSP titles (two God of War titles and Daxter) and The Order: 1866.
Bluepoint Games, due to their works remastering Sony titles such as Shadow of the Colossus and Uncharted, the former's PS4 iteration exceeding the work of the already cult-classic original.
Clap Hanz, for their already strong involvement with Sony in the Everybody's Golf series.
Supermassive Games for their work on the Until Dawn series and their assistance with LittleBigPlanet titles.
Quantic Dream, due to having developed only PlayStation exclusives for multiple years with Heavy Rain, Beyond: Two Souls, and Detroit: Become Human.
I feel the only one here that should be controversial at all with be FromSoftware since they have regularly made multiplatform titles and their acquisition is not only unlikely, but would result in a massive PC gamer backlash for their loss of the Dark Souls development team to Sony.
