The Japanese Persona 5 website has a countdown timer set to expire on May 5, but it's unclear what it will reveal.
The site has a hat with a flaming mask and the words "Take Your Heart" and the timer, but that's about it. It could be a new trailer, or a release date reveal, or maybe the game will receive a surprise release on May 5, though I can't imagine that last option will be the case.
