According to this schedule, it was supposed to open in Fayetteville in September. I haven't heard why it did not and I haven't heard of a revised opening date.
When it does open, you can still get the icon. In fact, even if you have visited it at another location, you can visit it again and get another "find" added to your icon count because it will be listed under a different GC number.
