I know I might be far too optimistic, but besides the titles OP wrote I hope this is what the studios are working on:

SCE Japan
The Last Guardian/The Legend of Dragoon/Arc the Lad/Wild Arms

Naughty Dog
Uncharted 4/Crash Bandicoot (Crash recently disappeared from Vivendi's list of owned IPs)

SCE San Diego
Warrior's Lair

SCE Santa Monica
New RPG IP/God of War IV with new protagonist eg. Norse or Egyptian mythology

SCE London
The Getaway/Eight Days (Mark Simmons worked on an unannounced AAA character action game at Sony London studio)

SCE Bend
Syphon Filter

Guerrilla Cambridge
Primal

Sumo Digital
Little Big Planet 3 (http://gimmegimmegames.com/2013/06/little-big-planet-3-leaked-via-resume/ )

From Software
Demon's Souls 2

Level 5
Ni No Kuni 2 (http://www.gamespot.com/news/nino-kuni-sequel-possible-if-ps3-version-succeeds-overseas-level-5-ceo-6372163 )

Insomniac Games
Ratchet & Clank/Spyro the Dragon (Spyro recently disappeared from Vivendi's list of owned IPs)

I wouldn't rule them out. Golden Abyss was just as good, if not better than Uncharted 1 (minus the touchscreen gimmicks). You never know what a team is actually capable of until you really give them a shot. The difference between Uncharted 1 and 2 is probably the biggest I've seen in any sequel this gen. Hopefully Bend surprises us just as much as Naughty dog did.

Also I am a Vita owner but I'm completely down with Bend moving onto the PS4, I hope this rumour is true. It gives the 2 naughty dog teams an opportunity to work on something new.

How big is Sony Santa Monica anyway? I mean they are working with RaD on 1886 and are probably supporting a bunch on downloadable games. And I am pretty sure they are working on a new God of War game. I mean how much can they be making?

Do you think Sony will land a few second party deals like they did with Quantic Dream?

Santa Monica this gen was two seperate divisions:  Internal Team (Worked on God of War) and External Team (Consulting Group)

It has been confirmed that Santa Monica has broken up their internal team into two seperate entities.  One worked on God of War: Acension which released earlier this year and will likely handle God of War from here on out.

The other one is rumored to be working on a title that possibly has elements of

-Open World

-Magic based powers

-shooters although it sounded as though they were looking at shooter experience in general and not specifically FPS or TPS, which could entail more than another rehash of the "HERPDERPITY SHOOTERFIC GENERIC SHOOTEMS X" genre.

Giant Sparow (unfinished swan) is also working on a new game and considering the joblisting for a producer they had up a while ago said something about working close with sony, it might be more or less save to assume they'll publish it.

And does Sucker Punch have a second team? i remember reading something about that.
SCE Japan is also working on freedom wars for the vita since you seem to be listing these as well.
San diego studios is probably working on another game as well, they usually do more than just mlb.
And i'm pretty sure insomniac is or will be makeing another ratchet and clank game to go along with the movie.

thanks for the info, will add to OP

I know sucker punch have been hiring and got a mo-cap studio, but i've heard nothing on a 2nd team

Giant sparrow have a three game deal like thatgamecompany had

I guess the reason Sony shutdown so many studio was to shuffle the resources and have two teams across its existing studios..

And I don't think Sony will source off new gen iteration of Uncharted, their best selling franchise to some other developers, Heck they didn't even outsource Heavenly Sword 2 to any other developers. And I guess they would know how much Uncharted depend on cinematic presentation.. and there is no other developer in the industry who could do justice to a full fledged uncharted game like the way ND does.

And lastly I had heard the rumor, that Resistance 4 was being developed by SCE Bend, So either its R4 or Syphon Filter 5

as for rest of the studios, I want Getaway and Eight days back (London Studio),

Santa Monica Studio
- Heavenly Sword 2 (its either SMS or ninja theory will return)
- Folklore 2 (SMS- open world, magic based?)
- or two new IP (Honestly they should give GoW a rest and reboot it late in the gen)

Naughty Dog
New IP - From UC3 team
Uncharted 4 - from Neil Druckman (the last of Us & UC2 team)

SCE Bend
- Resistance reboot from another dev wont be a bad thing
- Syphon Filter 5 or a new IP

Project Siren (Japan)
-New IP

Eat Sleep Play
- Pursuit force (PS4/vita)

So to sum up out of 20 games in development, 12 are new IPs so 8 will be sequels, minus Infamous and killzone, we are left with 6. I hope 6 of them are MediEvil, Heavenly Sword 2, Folklore 2, Syphon Filter 5, The Getaway and jak and dexter.. But i m sure in those sequel there is Sports Champion 3 too

For Vita.. Patapon Vita, Pursuit Force

I disagree. Their best games imo have been the UC and TLOU games and I would rather they continue with these. Having said that, I wouldnt mind one of the two teams continuing these two IPs (alternating every two years), and the other creating a new IP.

Im hoping for another level 5 game, hopefully a sequel or something similar to Ni No Kuni

If that is the case; I really hope for Naughty Dog to do Syphon Filter reboot then.
