In terms of independent studios, I can see Sony being interested in:
- Camoflaj
- Creative Vault Studios
- Ember Labs
- Hello Games
- MiHoYo
- Arc Systems Work
As well as Deviation, Firewalk & Haven, depending on the success & reception of their projects. I wouldn't count out Sony buying a massive publisher like Capcom or Square either. I mean, Sony buying a publisher is a massive undertaking for them, but they're also in the best position financially than they've ever been, and they have the capital to make strategic investments to weather the consolidation storm that is about to hit the video game industry.
