Quoted from nicoga3000:
What I have heard is that the licensing fell through, but that Stern is working hard to sort out the issues with the license holders. I wouldn't be surprised if we SEE a Kiss pin, but I don't think it's next (I think that goes to a VE or GoT).
Here is the quote from Pinball Magazine:
. . . Designer John Popadiuk confirmed he was unable to secure the KISS-license after displaying his KISS-prototype at the Midwest Gaming Classics show. He had been informed the license had been secured by Stern since then. Please note that Stern have not confirmed they secured this license and we apologize if a previous listing may have given the impression they did. If true, it would most likely be a title for 2015. On the Pinside Forum former pinball designer Mark Ritchie has been briefly rumored as the designer of this game, but when asked about it at Pinball Expo 2014 Mark denied being involved. If any of these rumors are true the most logical designer to be working on it would be John Trudeau.
