Just screwing around in Campaign to level my PLD and farm some Voiddusts before a little Christmas dinner outing, and I happen across this on BluCheater:
An UNCONFIRMED report has stated that, sourcing Japanese gaming magazines, Seekers of Adoulin has a release date: March 27, 2013.
Been searching the web for the last half-hour for ANY confirmation, and have found nothing. Stay tuned.
EDIT 7:40 PM 12/25: At least one Japanese gaming website has stated it, so Gamer Escape has also reported it from there.
