What some may consider Atlus' best title to date is getting an enhanced version to the PsVita. The game will contain multiple features including trophy support and updated visuals. Here is some small information gathered.
"Presona 4 will see a re-release three years after its original launch. This time, it’s coming to PlayStation Vita.
Persona 4: The Golden is an enhanced port for Sony’s new handheld, adding new characters, movie events, animated scenes, and more. It will include 1.5 times the amount of voice-overs seen in the PS2 version. Marie, voiced by Kana Hanazawa, is one of the new characters.
Out in Japan in spring 2012, it will utilize the “communications capabilities” of PlayStation Vita."
Also on the plate is some information on a persona 2d fighting game and some small info on Persona 5
"A bit more surprising is Persona 4 The Ultimate In Mayonaka Arena. Atlus is teaming up with Arc System Works for a 2D fighter that will be released first for arcades in Spring 2012, then for PS3 and Xbox 360 in Summer 2012. The game is being developed by the BlazBlue team.
The Ultimate in Mayonaka Arena has a new story that takes place two yeas after the events of Persona 4. Characters from Persona 4 and Persona 3 will feature in the game.
Famitsu also has a few preliminary details on the next numbered entry in the series, Persona 5. Basic preparations for the game's development have been completed, with the usual staff members in place. That includes Katsura Hashino as director, Shigenori Soejima as character designer, and Shouji Meguro as main composer."
