The only reason they announced it so early was to keep people around waiting for a free dlc after all the issues it shipped with during its release. It would be nice if they delivered on what they announced as "planned" for this month, but I won't be shocked if it comes out in July or later. I also think they've realized that they can't keep everyone around with a little bit of free content without also fixing issues with the game. So my fingers are crossed that they actually deliver some big fixes and improvements in conjunction with the dlc.
You can uncross your fingers bro, sure it hurts by now lol. They made another twitter tweet saying that they ARE working on an update to accomodate the DLC when it's finally released. I was hoping to, but to read that they actually are settled 1/2 of me down.. still getting unruthlessly anxious now.
Screenshots/video/something to SHOW us? Instead of "Our DLC is coming, the date? Only Houdini knows..."
