I also don't think it is good business sense to let the world know too early what the next machine is without selling a heap of the current ones just released as some people would hold on to their coin for the next one. Don't get me wrong kas I wasn't personally interested in getting a AC/DC so I would love to know what the next one is as well as JJP next one hoping for a Elvira one.
It's like the Transformers LE - they are still available even now.
