Persona 4 Dancing All Night came out recently in Japan, and their limited edition bundles included an exclusive trailer for Persona 5. Fortunately, someone posted it via YouTube...
According to Atlus, the game is expected to be released later this year.

Square-Enix Who!!????? SMT/SMT Persona >>>>>>>>>>>>>>>>>>>> Final Fantasy tbh!
Also, if you're interested in getting into Persona or other games in the SMT series, ATLUS is having a sale on the North American PlayStation Store. P4G is $14.99, and P3P is $9.99! But chances are you don't have a Vita, so you can get the PS2 versions for $9.98 altogether!
