Actually, if you know the whole story of how Disney bought the Muppets, they were pretty stupid about how that whole thing went down.
I have NO idea how I would swing it, I just know that I would *have* to buy if they came out with one. I LOVE the Muppets and the idea is great.
...but, having said that, the theme itself hasn't proven itself to be overly strong lately. The most recent movie was a disappointment in Disney's eyes. The characters, while well known to an older generation, are not perfectly well known to kids today. That's kind of what the movie was all about, actually, and it rings true. Thanks in LARGE part to how Disney acquired and then more or less squandered the Muppets for *years*, they are not as big as they once were. I think that a Muppets pin would sell strongly to a subset of pinball collectors, but would actually be a pretty big route flop - it wouldn't earn tons from kids, who both don't play pinball anyway and don't really know the theme, and it wouldn't earn tons from adults because if you put the pin at the local bar, it doesn't seem very many to be playing a machine with Ms. Piggy doing call outs.
With all that... I voted Gonzo. Love that guy
