I don't get the fuss. We've been patiently waiting for this thing for YEARS. Why is it suddenly so urgent to know the exact release date right now?
Larian will give us a date when they have one for definite. They always have. If they kept giving us false dates when they didn't really know and were only guessing, that would be pretty annoying, but they don't. I prefer the way they do things now, thanks.
Markets change. Publishers alter their ideas of just when a game should be released. Stuff happens. Yelling at Larian for things they have no control over is a bit pointless, don't you think?
Look at it this way: a later release means a more patched up and more instantly playable game. That can't be a bad thing, right?
