This wouldn't be the first time the Australian Classification Board has revealed an unannounced game. Atelier Rorona Plus was rated by the Board around a week before it was officially announced.
Even if this game doesn't get announced for PAL regions, Persona 4 Arena Ultimax can still be imported and pre-ordered by fans from these regions as the game has been announced as region free.
Pre-order for PS3 (in Japanese): Play-Asia
