This list only includes first party studios(devs owned by Sony), and second party studios (devs, that are not owned by Sony, that are making, or have recently made games both published, and owned by sony).  This list does not include third party studios that are making Playstation exlusive games that are not published by Sony.

In total, Sony is publishing 25 announced upcoming ps4 games:

15 are new IPs (The Order 1886, Bloodbourne, Kill Strain, Drawn to Death, What Happened to Emily Finch, Everyone's Gone to the Rapture, Wattam, Until Dawn, Alienation, Rime, WILD, Helldivers, Big Fest, Guns Up, and The Tomorrow Children)

2 are reboots(Rachet and Clank, and Shadow of the Beast)

3 are ports (Journey, Hustle Kings, Super Stardust Delta)

1 is a remake (Tearaway Unfolded)

1 is a spinoff (Fat Princess Adventures)

3 are sequals (Uncharted 4, MLB the Show: 15, and Hot Shots Golf 7)

E3 cant come soon enough.

I just think its interesting that we know so little about what all of the first party studios are doing. only 4 games are officially announced out of all of those teams is really intriguing.

I am interested in finding out what Sony Bend and Guerrilla Cambridge are up to.

From what I understand, Japan Studio doesn't have traditional teams like other studios. Instead, a small group will do the early work then other people will come over as they are needed. When the former head of Sony Santa Monica took over, he said there were like a hundred separate games in development and he had to cut a lot of them out as he attempted to form some kind of order.

I'm eager to see GT7 in action. As great as DriveClub looks, I think GT7 will make everything pale in comparison. :P

Yeah I made a note of that at the bottem of the chart.

Interestingly, when I was building this chart, I wanted to try to break down Japan Studios into individual teams.  So I started watching credits of individual games.(Knack Puppeteer, Loco Roco, The Eye of Judgement, and the last Ape Escape Game)  Knack's team is made up of a hodgepodge of devs from Loco Roco, The Eye of Judgement, and the last Ape Escape.  On the other hand I could barely find any of Puppeteer's devs in one of those previous games.

All we really know about Japan Studio is that given its release history, it contains 4-6 teams.

I wonder why the MLB series can never get a million seller. As a series its passed over 15 million so of course its a lucrative franchise, but I feel it can so better

MLB probably sells a lot better than what this website indicates. It charts highly on NPD every single year, often for multiple months. 

As for the main topic: I'm most interested in what Bend, Guerrilla, and Santa Monica are up to. Definitely wanna see Guerrilla's dino-RPG!

It is quite impressive. Yeah it confuses me that MS continues to say they are in gaming for the long haul and yet they haven't acquired a list of studios even half as impressive as this one.
