It's impossible to tell you when the game will be released since there is only a teaser posted on Vimeo website. There is no release date or something related to this operation. You can check the teaser by yourself using the following address: http://vimeo.com/89011061
Unfortunately, this is the only resource available for public regarding this game and its release date or information. Since the first game is released on BigFish Games, your best bet is to access the site from time to time to search it.
