Wow that's weird. When you touch the squares in the site long enough a teddie appears. Maybe this isn't a Persona 5 announcement after all...
It's the various portraits of teddie, and when you match the three of them it resets.
Could this be a Persona 4 Golden X 3DS version? Or a Persona 4-2 for 3DS and PS VITA?
