Sony acquiring Supermassive games.
This seems highly unlikely since they've been working with Bandai Namco for a few years on The Dark Pictures Anthology games and even ported another Bandai Namco published game Little Nightmares II to PS5 and Series X|S. Their last game with Sony, Bravo Team, was a critical bomb so that probably soured their relationship.
A lot of Sony second party studios have left recently. Clap Hanz, developers of Hot Shots/Everybody's Golf since the second game back in 1999 released Clap Hanz Golf on Apple Arcade last year.
Qunatic Dream is doing a new Star Wars game that doesn't seem to be published by Sony.
Ready at Dawn and Sanzaru are both owned by Meta.
Seems like most developers of PS VR exclusive games have already released new games without Sony.
One team that seems to go mostly unnoticed is Creative Vault Studios. They've only ever worked with Sony and may be worth picking up for PS VR2 development.
