I don't have any hard figures or anything, but the response to the UnLeashed line appears to be lackluster at best. Though better than the past incarnations of "statues," the UnLeashed somehow didn't spark my interest the way I'd hoped.
I do appreciate the point of them though. By "unleashed," it is easy to see how you've captured the inner strengths and pent up desires of each character. Naturally, the males are full of disasterous fury while the females take no shame in displaying their passionate selves. From that aspect, you've captured the essence of all these characters quite well.
However, after some discussion and little nudges here and there, I'm thinking that a better idea would be to create a line of "statues" based upon the various poster art that we've seen for the past 25 years. I feel that this kind of product would be more recognizable to a wider consumer audience than the UnLeashed imaginations of the Hasbro design team.
In addition, the card backs could double as large puzzle pieces, that when put together with other cardbacks from the same group, a rendition of the original poster from whence they all sprang could be constructed and used as a backdrop for the complete set of figures (for that particular poster).
