Sony own many game development studios and some even have multiple AAA teams and we only know what a few off them are making. E3 is coming soon, some will make an announcement at E3 while others will wait for later events.
You (probably) know what they have made in the past, so which of the PlayStation studios unannounced games are you most excited about?
Guerrilla Games
Cambridge Studio
Evolution Studios
London Studio
Media Molecule
Don't expect developers who released a game in 2014 or 2015 to announce anything at E3.
