Now, unless he is publicly lying for some odd reason, it looks like, as of this Friday, the skill and rune systems still aren't finalized. If they aren't even done deciding on what to do with two of the most important systems in the game, there is no way they have a release date set.
I realize most people weren't expecting a release date next week, but for the foolish few (including me) who were, this is depressing, but not incredibly surprising. No such thing was even mildly hinted at by anyone from Blizzard. I need to stop reading a certain blog.
