A few days ago, Atlus posted a countdown timer on the official website for Persona 5. What exactly was at the end of the timer was a mystery, though it was easy to conclude it would be a significant announcement of some kind. Atlus announced today that at the moment the countdown timer expires, the Developers will be hosting a livestream that will reveal "all new information"
Fortunately, it seems as though we will be getting some good news at the other end of the countdown, so we might very well still get that Summer 2016 release date that the game was pushed to.
Time will tell.
