I think they knew since this entire thing started that people would want an ETA. Since they haven't given us one.....they probably don't have one. Any amount of demanding and threatening is not going to get you one. So no, it is not worth trying. They already know how badly we want one.
And yes, any visit from an EQ2 official to this forum would be pretty rare, and they probably wouldn't even do it now because all they would see is stuff like this. What's the point?
