Initially the offer to upgrade the PS3 version of Final Fantasy XIV: A Realm Reborn for free to the PS4 version was supposed to expire at the end of the year, but during the latest Letter from the Producer Live Broadcast Director and Producer Naoki Yoshida mentioned that the promotion will be extended to March 31st, 2015.

In addition to that, Yoshida-san also mentioned that the 14 day free trial for PS4 and PS3 will start on December 11th for PlayStation Plus members, while those that aren't subscribed to PlayStation Plus will be able to enjoy the free trial starting on Christmas Eve, December 24th.

If you have a PS3 or a PS4 (especially Sony's new console, since the game looks amazing on it) and you still didn't jump on Final Fantasy XIV: A Realm Reborn, you should really give it a try. It's a great game.
