I've just heard in the Podcast Boardgames Insider (where Ignacy is a host) that the game won't be ready for an Essen release. It was Ignacy himself who said that they would be soon making an announcement. As someone really excited about the game I'm sad to hear this, but in the other hand this means he is making the game better and playtesting it appropriately.
When you gain this card from the deck, gain 2 Clues. ;)
I kind of suspected this, and see it as a good thing.
In a recent interview (3 weeks ago?) it sounded like they thought they still had some playtesting and/or balancing to do. And going by another company's recent launch, Portal may want to do even more app testing before release.
I'm also glad seeing that they are taking their time to make it better. Recently companies are so focused in pushing their games into the market in order not the lose the buzz around their games, that sometimes the games lack a couple more months of playtesting. I hate to buy a game and some months later have to check an errata because some cards and some rules are not ok. I hope they take the necessary time to make this game as great as he expect.
