I hope you like the Persona series, because you're about to get a LOT of it. Atlus is hard at work on no less than three different games in all, Famitsu reports (via Japanator). First up is a PlayStation Vita port of the PS2 game Persona 4.
The Vita release will carry a new title -- Persona 4: The Golden -- as well as a new character (Mary), additional voice-acted dialogue, new animations and more. That's a planned spring 2012 release (in Japan only at first, I would guess), as is Persona 4: The Ultimate in Mayonaka, a 2D fighting game that will arrive first in arcades before seeing a console release next summer.
Atlus is also naturally working on the next core game in the Persona series. Very little information is revealed, though the core development team is returning and they're planning some changes. What those changes are remains to be seen.
