I doubt it, because the season pass was just announced, and you don't do that sort of thing until you're in the VERY late stages of completing the game.

But, I also kind of believe it, because games usually go Gold (ie they're officially finished and they send the master in to be manufactured) within a month of the game's release.

Really up in the air. I hope to god it isn't, but I won't buy it until we hear from a legit source. (Square themselves.)

It is possible they're delaying it so that it's a Neo Launch title.
