While we don’t yet have an official release date from NIS America for the upcoming PS4 exlusive Disgaea 5: Alliance of Vengeance (besides a generic “Fall” window), a hint might have just come from retailers.
Both Amazon and Gamefly have now pegged the release date on October 6th, which does fall within the Fall release, and doesn’t look like a Placeholder (normally placeholders in that period are either indicated as September 31sth or October 1st).
October 6th also falls on a tuesday, which is the usual update day for the North American PSN, adding solidity to the date. Of course this should be considered a rumor until an official release date is announced by Nippon Ichi or Sony Computer Entertainment.
Update: the same date has appeared on Best Buy‘s website.
