I will say, as disheartening as it is learning about some of these internal projects not panning out, Sony is also in their most aggressive phase when it comes to M&A.
While the majority of investments will be made towards multiplayer/live service/mobile developers, I wouldn't rule out Sony going for a developer like Remedy, or single player developers like Kojima Productions. Promising partnerships like Housemarque and Bluepoint aren't going to be slipping through their fingers this generation like From Software or Atlus did.
