Two popular Japanese fan sites (eLeMeN and FF14Fan) have reported that Square Enix will be having a special event to mark the launch of Final Fantasy XIV on September 14th in Ebisu, Japan at The Garden Hall.
Japanese testers were able to enter a drawing until August 23rd. 350 of those entries will be selected to attend the event.
The event will last roughly an hour and a half with the doors opening at 5:00PM, the event starting at 6:00PM and then wrapping up around 7:30PM.
No word yet on whether similar events will occur in other areas of the world.
