It seems as though it has become an industry standard to make an announcement of an upcoming announcement. Square Enix took to PAX Prime with information on Final Fantasy 15, which ended up to be an announcement about an impending announcement.
The developers know when Final Fantasy 15 will make its release, but have only decided to announce that it is coming next year. Don't be silly though, the game isn't releasing in January or February of 2016.
When the new year rolls around, Square Enix will reveal the release date specific (like the month and the exact date) during a special event in March 2016. Notice the event doesn't have an exact date either. The vagueness around the dates can definitely be viewed as a strategic move to increase anticipation for the game, but it feels like Square Enix is unsure of what dates to commit to… That, or they are going to reveal the release date like Bethesda did for Fallout 4 — around six months before release.
Either way, if the demo was anything to judge Final Fantasy 15 by, it could be pretty fun,
