Sony Bend
Guerrilla Games
Guerrilla Campridge
Sony Santa Monica
Media Molecule
London Studio
Quantic Dream (second party)
Japan Studio (most likely)

Edit : TLoU team have another game in development to, its still early in production though. 

That reminds me, wasn't there a tweet or something about London studio being at GC? but no show..either it was fake or cut out at the last minute, though i don't see why a London studio game would be saved/moved to TGS
