The theme is awesome. If it is manufactured by Stern, I would not be interested. No use in having an expensive ornament. If it were made by another company, I would be interested, but I would not be part of any pre payment plan to buy the game.
I hope it is a future title.
Unless I was dreaming at the time, I was listening to a podcast about 3-4 years ago where Jack Guarneri (JJP) announced there second or third game would be Elvira. This would have been before WOZ hit the streets. I never heard anything more since then.
Perhaps Stern chased the licence before anything was signed with JJP, as they did with Kiss after JPop announced Kiss. Or perhaps this is a JJP.
