Persona Q, a 3DS only Persona 3 and 4 cross over with chibi characters and graphics.
Persona 4 Arena 2 Ultimate - which we already knew was coming.
A Persona dance game... on Vita, looks closer to Elite Beat Agents with Persona characters.
Still hoping for a Persona 5 announcement since the stream is still going, and that's the sort of thing they would leave for last.
edit: and finally, they announce Persona 5 in Winter 2014 on the PS3. However, they don't show anything besides this video:http://www.youtube.com/watch?v=2mZssK05WYo
