Having another studious is not bad either, you also need to remember, Sony attention now are divided into two platform, which are VR and Mobile devices (smartphones ). Also Sony capability on making first party ip in a year is limited to just one or two ip. With having another studios they will likely to produce more in a year. Of course they can just ask 3rd party studios to make exclusives games for them but having a studio that is inside your policy will be much better. And also like u said Japanese developer can be bought by money especially Microsoft , so . Having more is not a sin. 

TBH, I don't think Sony has enough 1st party developers. Sony's Japanese developers that works on the PS Vita are worth chum change for the most part ...

The amount of truly worthwhile content Sony's 1st party generates is barely passable as it is IMO so they need more in-house studios and especially Japanese in-house studios as well ...

Sony has already established that they are not interested in acquiring studios.. Instead they are focusing on building teams within existing studios.. Its better to have another game from studios like SSM, ND, GG, SP. I just wish they dont shutter down more studios (Media Molecule, Sony bend)

P.s. Personally I think Sony might acquire Blue points game, for their technical expertise, But if PS5 has BC to PS3, then that acquisition is very slim

As said above, Sony doesn't need to buy more studios. They just need to expand the ones they already own, or establish new studios.

I think expanding Naughty Dog, Guerrilla Games, Bend, Polyphony Digital, and Sucker Punch to Two Teams would be a good start. Then I think they are in dire need of a JRPG Studio in Japan. Those expansions should be enough for them to continue successful franchises, and continue to deliver new franchises at the same tme.

I feel that continuing to expand their exclusive offerings, while maintaining an industry leading, and ever rising quality bar, is key to maintaining and growing the Ecosystem. They need to continue to deliver on what the expectations they have built, while also trying their hand at new genres, and formats. If they can continue to grow to the point where they are delivering Uncharted/God of War/Detroit/Spider-Man level games, across TV/Gamepad, VR, and the Online Space, they will cotinue to see great success.

One thing I see for certain, if they do not grow, and just continue their current status quo, they will eventually begin to loose ground. That is a fact everywhere, if you do not continue to improve and expand, eventually you will start to see your competition gain on and/or surpass you. Being great is not good enough, you can maintain what made you the market leader, but in time, even if you do everything right, but only maintain, you will fall behind. Everything is about growth, and if you want to stay ahead, you have to find the balance between continued innovation, and over accelerated progress. You have to put things out that imrpove, even when people are not asking for it, yet you can't put things out to fast or people will reject it. It is a crazy good game in itself.

Hopefully Sony, Microsoft, and Nintendo all have road maps for expansion, and innovation. We need them to keeping fighting off Apple and Google.

Thanks for letting me rant.

More like 3 -4 first party published games per year. And thats plenty from an exclusive standpoint any year. As opposed to MS one or two per year.

Sony doesn't need more studios. If they need to do anything its to get more out of their studios and partnerships.

I don't think Sony NEEDS more studios, but I can certainly be pleased if they doubled the number of studios and released games.

A console can never have too many exclusives. What might be debated is the type of exclusives they have. For example it seems like they've discontinued Gran Tourismo. Not sure if that is a good idea or not. It's never a bad idea to have plenty of variety in exclusives too. But, other than that thought, more exclusives is always good.

They have not discontinued gran turismo. And I don't know where you are getting that.

Didn't think "Sport" was considered part of the main series.  It's certainly not as popular as earlier entries.

You are right on the need to keep improving/expanding as the best way to keep ahead.
