All the console versions have already been released and the website says May release. I have emailed them to no response and wondered and hoped that someone else had information on it or any other telltale games. Perhaps some beta testers?
On the developer's (TellTale Games) forums, they said that they were just going to put extra time into optimizing episode two. They also said that they were further optimizing the first episode. Every episode will come to the iPad, the developer is just trying to make the game run as well and look as good as possible for the iPad.
