The Persona series is alive and well!
Persona 5 has at last been confirmed and is due to be released in Japan on the PlayStation 3 in Winter 2014.
Check out the trailer below.

They’ve also announced a more unexpected game ‘Persona 4 Dancing All Night’ for the PlayStation Vita.
It is described as a ‘sound action’ genre with release planned for Autumn 2014 in Japan.
From the trailer we can see the cast of Persona 4 are back along with a new female character.

Atlus must be hard at work with the Persona series, an animated film of Persona 3 has been released in Japan and a new game for the Nintendo 3DS ‘Persona Q Shadow of the Labyrinth‘ was announced as well with June 2014 as the release date. This game features characters from both Persona 3 and Persona 4 and I wonder if it will carry on the story told when the two games crossed over for Persona 4 Arena.
Additional content for Persona 4 Arena is also expected to be released for the PlayStation 3 in Summer 2014. It adds more story to the game as well as new characters and has the updated title of ‘Persona 4 Arena The Ultimax Ultra Suplex Hold’.

None of these games have been announced for America or Europe yet.
