Chatted with Dennis a good bit at Expo and i seem to remember him saying that that the next thing he was doing with Stern would be a full/modern machine. Also, i got the wink-and-a-nod impression from him that there might be an Elvira 3 in the works, but it wasn't clear which manufacturer that might be with.
Of course, there was a lot of alcohol involved so I could be totally wrong about all of this. I hope not though. I'd love to see any new machine from him, particularly another Elvira.
