Atlus is teasing a Persona announcement. Said Persona announcement adopts the style of Persona 4. Atlus previously released all three of its Persona titles on PSP. We'll leave you to do the maths.
We suppose the big discussion here is not what Atlus is about to announce — Persona 4 Portable seems obvious, right? — but which platform it will be on. Both PlayStation Portable and PlayStation Vita are viable targets. Place your bets now.
