Bear-sona! Japan's Famitsu magazine has plenty to reveal in the Shin Megami Tensei Persona series, some expected and some "WTF, I guess that's cool, but really?"
First is Persona 4 The Golden, a Spring 2012 PS Vita remake of the genre-defining Persona 4 on PS2, which will bring a new character named Mary, new animations, and "wireless support for calling on others to help you when you're about to die in a dungeon". I'm not sure what that means, but I imagine that if you're playing with someone else who's playing Persona 5 nearby, The Protagonist can be revived by your friend when he's down for the count (probably by some annoying instant-kill Hama or Mudo spell)
Persona 5 also seems well on its way with all the staff members in place with director Katsura Hasino, character designer Shigenori Soejima, and composer Shouji Meguro.
On the strange side, Arc System Works, known for their furious BlazBlue series, will be turning Persona 4 into a 2D fighter for Xbox 360 and PS3 called Persona 4: The Ultimate in Mayonaka Arena. Also releasing in arcades in Spring 2012 and then for consoles in Summer 2012, it takes place two years after the who-dun-it mystery in Inaba and already features Protagonist, Chie, Yosuke, and Aigis (with their default Persona forms). I expect some along the lines of a cel-shaded Bloody Roar. (Yep, I totally referenced that.)
