Quantic Dreams new game is a lock for the show. Yoshida all but confirmed that during his EGX panel. Zoetis (the person that first said that TLG would resurface at this years E3 and was verified by mods) has said that PGW will be better for Sony from a first party standpoint than E3 was.
Wasn't Zoetis vetted by mods, so he obviously is someone in the know, at least when it comes to Sony?
I expect Sony will pull at least one shocker out of this event.
