I've been waiting for an FFXIV sale and haven't seen one pop up since Christmas. SquareEnix store is doing a 40% sale for all editions of the game. This beats Newegg's current 20% off sale. Great game for former WoW players. If you're interested in trying the game, the base game is completely free to try until level 35.
Also, the collector's edition is on sale, the first time I've seen it on sale.
