We shall see. Provided the September 12th reveal date of the new iPhone is the truth, I think the booking of the venue should have showed up already. Did it? I don't remember anyone talking about that anywhere. In the past the invites would show up shortly after the venue booking was revealed. Maybe a week after or so, I think.
If things are going along then we should start seeing info showing up this week. Venue booking, if not revealed already, and invites. eiC is on it though. As soon as something surfaces they will post it in the news. There are other sites too but I haven't seen anything so far.
I'm excited though! It's getting close!
