Sony might have the biggest amount of unannounced games from all the publishers this year. Uncharted 4 is the biggest game Sony is going to release after E3, it will be coming out 2016. Other than that you have loads of studios like Team Ico, Polyphony, Japan Studio, Sony Bend, Guerilla Games, San Diego Studio, Sucker Punch, Pixelopus, Sony Santa Monica, Evolution Studios, Media Molecule, and smaller studios that are within Sony. You have 2nd party development studios like thatgamecompany, Giant Sparrow and Quantic Dream.
We have games like Hellraid that is going to be coming out first, there's a behind-the-scenes trailer recently released for the game.
Tales of Zesteria was also recently announced to be coming this year on October 16th.
Polyphony is most likely working on Grant Turismo 7, so we might see a trailer for that. Don't expect a 2015 release though, because there has been nothing about the game that's been shown so far. The game most gamers want to hear from is The Last Guardian, which has been said several times to be still in development and not cancelled. Guerilla have released some concept art for the game, otherwise there's not been a lot of info about the game. Uncharted 4 is probably going to be shown even with the delay. It was last shown during Playstation Experience in December, and The Nathan Drake Collection might also appear since it was recently announced. Media Molecule is working on something new, since another company took over Little Big Planet series from them. Sony Bend, Studio Japan, Evolution Studios, Sucker Punch, thatgamecompany, Giant Sparrow and Quantic Dream are all working on unknown projects. We can only look forward to what Sony have up their sleeve this E3. Many of the complaints about the PS4 have been the lack of the exclusive. Let's see if they can silence those critics.
