That doesn't mean they discontinued GT. Studio still exists and they may be working on a GT7 or not, but even if you don't like GTS, consider it another game or doesn't sell much doesn't mean it was discontinued.

Didn't say I "know" its discontinued.  Just saying it seems that way.  GT6 came out 5 years ago and we haven't heard anything about GT7 yet.

my selfish wish is that Sony acquire/build up atleast 1 dedicated JRPG studio (AAA lvl budget/production values), but I'm aware that there probably just isn't big enough a market for these games to support that *sigh*

Given exclusives are among the few quality games these days Sony should make more studios, and I say that as a Nintendo Switch only gamer.

PD is quite limited in size, so since they were making GTS it would be quite impossible to have GT7 at the same time. At earliest expect GT7 by 2020 as an evolution of the model of GTS (using all the cars and tracks they have been releasing).

Well there is market if they can make the marketing good enough to push a lot of sales. Dragon Quest and FF still manages good numbers. Sure starting from scratch or sequel of old games will be a harder thing to get the level of DQ and FF, but Sony earned a lot of good will this gen, so if they really commit on this JRPG studio they may see good success.

Nothing wrong with not being your cup of tea but recognizing they are good and should have more. As I also would like Nintendo to keep increasing their studios to deliver ever more games on Switch.

That's just happen recently. On top of that, they could have better launch in PS4 early years. Also in the future Microsoft will not be the same, Sony cannot do the same thing they need to do 3 times better. Microsoft in the future will be full gear like Xbox 360 days and will start asking Japanese games developer to involve and plus all the first party studios they just bought  will make them like PS4 revenges day plus the money to buy exclusivity, and also unlimited resource on marketing minus the DRM fiasco. 

I am just to afraid to imagine , they want some revenge .  

Soby’s Doing great on that front, no doubt, but there’s still a few studios that I think it would be cool for them to buy, namely Kojima Productions, Insomniac, and Quantic Dream. Supermassive and Bluepoint would be good too.

It isn't.

Same way the GT Concept series in the past wasn't a part f the main series. The concept and sport installments are like stop gaps between main series.

And they are still releasing content for GT sport to this day. So no, nothing indicates that GT has been or is being discontinued. If anything it all points t a very fleshed out major release for GT7 probably on the PS5.

Anther thing people don't know about PD, is that like some other studios (konami used to do this a lot too) they make smaller slices of a game (think like a very big sold demo) that they release and take the proceeds f that and use it for the development of their main game.

It wouldn't hurt them to acquire a couple of more studios- but they definitely don't need to. They already have an awesome stable of first party studios- as well as great partnerships with third party studios to make exclusive games for them (i.e. Blue Point, Insomniac, etc.) I'm just worried that Microsoft is going to snag one of those studios first. But as far as Sony goes - their already established studios have really grown over the years and are now some of the best in the industry. Looking ahead - their exclusive pipeline is ridiculous:

Days Gone
Dreams
Concrete Genie
Wild
Last of Us: Part II
Ghost of Tsushima
Death Stranding
Final Fantasy VII Remake
God of War Sequel
Horizon: Zero Dawn Sequel
Spider-Man Sequel
Gran Turismo 7
Blue Point's next project (Demon Soul's Remake?)
Ueda's/ Team Ico's Next Project
Most likely a Bloodborne Sequel

Sony will be just fine!
