I really don't know from what part of what I said you extracted that there isn't a set time even within the Staff.
Players were given a date for when the server will be up according to the plans. Maybe more specific information will be given before the actual release, maybe it won't. It's not for me to decide to divulge that kind of information, but if that's what's decided, players will be informed.
The whole "disclaimer" in the original post in this thread is a lie, though, which is what I meant to address. If people are given a time beforehand or right when it opens, the flood will be the same. For the time being, players will just have to wait and see what happens next.
