There's a sequel/update/thing coming out for the best fighting game of the year, Persona 4 Arena. It's called... it's called... it's called Persona 4 The Ultimax: Ultra Suplex Hold.
Oh, and Junpei and Yukari from Persona 3 are back - Junpei is some kind of baseball star (!?) and Yukari is now an actress on a Super Sentai show (!?!?). Also, some random new dude that people are speculating might be involved with Persona 5 called Sho Minazuki, but who cares when THERE'S AIGIS PILEDRIVING YU.
ULTURA SUPUREX HOLDOH
It's out in Japan this year, and probably NEVER for Europe, because Atlus hates my money.
