I'm not sure I'd classify Konami as "large distinct publishers/studios" anymore. Apart from the obligatory yearly installments of PES and BeatMania, they seem to mostly make gambling machines these days.
Interestingly, they're owned by Kadokawa Corporation, a large Japanese media conglomerate. Sony has a close relationship with From, so I could see them trying to buy the company, if Kadokawa was interested in selling.
Souls games sell really well, although not close to CoD or Destiny numbers. I feel like Elden Ring will be huge, though.
