GamesCom 14 could be interesting, more than other years. Bioware will show something new there, Microsoft will unveil the first gameplay for Quantum Break and Sony could reveal new software in Cologne.
The PlayStation Company has posted this ephemeral trailer:
Just 11 seconds of furtive pictures.
Personally, I would bet for a re-announce of Until Dawn. This horror game was being produced for PS3 and was showed in different events, but suddenly Until Dawn vanished time ago. Sony could have redone the game for PS4. It could be a great game for Project Morpheus.
