I think a lot of people are gonna calm down when it does.
Doubtful. People will be complaining about how unbalanced it is. I dont see why everyone is even getting excited about pvp in this game. It's nothing but an after thought. No ladders, no rewards, nothing. It wont stay fresh for long without some kind of carrot dangling.
I think a realistic hope is October. Pre release I had thought August but they have to adjust the post launch balance issues first. Even if 1.0.4 hits within the next two weeks I still think October is safe.
