hmm are you sure? perhaps another delay by Sony since everybody tries to leak it.
Alot of people are talking about this big acquisition now.
Maybe they delayed it, or maybe not.
People like Greg Miller or Jeff Grubb have some credibility but they heard 'last week' and nothing. Geoff also mentioned while ago Sony making a big acquisition and unless he meant Haven (I doubt it) we're still waiting. The thing is, as I remember the big acquisitions never got leaked.
We know Sony will continue acquiring because Jim Ryan said it, so pretty likely they or their "sources" are only making a guess, like us.
We don't know if the next Sony acquisition will be big or small. After making many smaller acquisitions with Bungie as exception, I think they may buy a publisher now. Specifically, a Japanese one with several very popular IPs with potential to make movies, tv shows or anime and with a good catalog to fill PS+. But to do this they should increase their budget for acquisitions because with the available one I think they won't have enough specially considering they have to share it with other Sony divisions.
If not, I think they'll continue with smaller acquisitions: a mobile gamedev, a support team (like another outsourcing studio) or VR gamedev studio. Or some mid sized gamedev who doesn't own top IPs but made at least some successful exclusives for them and has potential to continue making sucessful games and to grow (Arrowhead, Kojipro, Quantic Dream, Supermassive, ARC System Works...).
The thing is, they have been closing the fiscal year and a big acquisition would have been important to be included before or after closing the fiscal year and they would have planned to place the announcement where needed. So maybe in other weeks of the year, it could have been ok to delay it, but I think in this particular case not.
I think that if Sony would have a big acquisition announcement planned for last week, they would have made it there. I think this is one of these cases similar to the fake rumors of "Sony will have a big SoP coming this next week(s)" after months of no SoP -or at least not big ones- and nothing happens, or they make one without important announcements. But a ton of "insiders" and "leakers" kept pumping the hype machine saying they heard Sony was going to have a huge SoP. And when nothing happens they say 'well, it has been delayed'.
Same applies to the acquisitions: Jim Ryan says Sony will continue acquiring, so a fake insider says a few weeks later 'Sony will announce an acquisition soon", and then other fake insiders repeat it, some of them adding that is going to be a "big" acquisition and other one adding is going to be "next week". And nothing happens.
NOT Capcom or Square Enix
I think they, Kadokawa and Bandai Namco would be the best fit.
Bandai Namco has a lot of current and classic IPs, a great catalog of old classics for PS+, mobile stuff, license to make games of many anime top stuff and is the top Japanese toy maker which could be a great synergy to make toys of PS, Sony anime, movies and tv shows or Sony Music artists. They also make and own top anime stuff. Sony also wants to grow in Asia, and Bandai Namco make a lot of their sales from Asia, particularly Japan:
They are in a good finantial shape but a big stagnant, a push from Sony could be welcome specially to help them grow in the west but they aren't in a finantial position where they would want or need to sell. But they are too expensive Sony's currently their available acquisitions budget and have some business like arcade game development or amusement centers (same applies to Sega, Capcom or Konami) that wouldn't line very well with Sony.
Capcom is in a pretty similar position: many old and active top IPs with potential -or already in- movies or anime, a huge catalog of old classics to fill, arcade business... in their case a cheapar and more affordable price even if they could still be too expensive for their current available acquisitions budget (but they could rise it, have more than enough money to pay with cash any of these acquisitions). But are in a great finantial shape, better than ever. They don't need to sell and pretty likely won't want to sell at least now because they are growing a lot. Their net income:
Almost the same with Square. Like the previous ones are very appealing even if have a few business that may not be very aligned to Sony and may be too expensive for their current budget. Plus don't need and may not want to sell because they are in a great finantial shape and growing:
Kadokawa is cheaper and affordable with their current budget. Has several game publishers and development teams, dozens of PS exclusives since the PS1 days, some interesting IPs and a ton of anime, music stuff Sony may be interested in. They also have book/manga/magazine production and publishing labels that may not interest Sony even if it could generate good synergies with their gaming, cinema, anime and movies divisions specially if Sony helps them to expand beyond Japan. It may a pain in the ass to properly integrate them into Sony because Kadokawa has a ton of different companies who work in different areas, their teams aren't split into separate gaming/music/anime/etc divisions.
In terms of finantials Kadokawa is performing well but would welcome help to bump their sales (and this is why they made a deal with Sony and another one with Tencent). They don't need an acquisition but may be open to sell because it would really help them grow specially in sales.
So everything can happen, but I don't think Sony is buying any of these ones at least right now (more likely way later once they rise the budget). First because maybe only Kadokawa would fit on their current acquisitions budget (so the only they could afford right now unless they decide to rise it) but may not be that appealing for Sony due to the potential restructuring needed to properly integrate it in Sony and that many of their gaming IPs aren't that important compared to the ones from Capcom, Square Enix or Bandai Namco specially for potential movies.
But instead they have a ton of manga and anime IPs, some interesting gaming IPs and FromSoft. Plus in their acquisitons Sony, with Destiny as excepction, isn't buying top game IPs: they are buying instead focusing on teams that may support existing teams, covering certain areas where they don't shine or welcome help to grow (VR, mobile, remakes, ports, GaaS...) and specially experimented talent to create very successful IPs. And From Soft fits very well in this last point specially after the recent Elden Ring. Sony also always valued to acquire teams who had a long tradition of partnering with them for exclusives. And well, From Software has dozens of exclusives since back the PS1 days, and same goes for the non-FromSoft Kadokawa game publishers and devs: they have dozens of PS exclusives since the PS1 days too.
So I think Sony isn't buying any publisher right now, but if they are buying one right now, I'd bet is Kadokawa.
