I think people have their favorite characters and Vicki, Mike, and Stephanie would still sell. Besides, the new figure would have a different face and would add a new look to a scene. You might still want Vicki or Mike to appear for a more diverse look. A morphable character wouldn't be the Be-all and End-all figure that would banish the others. As diverse as it would be, you still wouldn't be able to do everything with it. A lot of people said something similar when Stephanie came out. Why a new female figure? Will this destroy Vicki? Vicki is still selling, even after the appearance of Stephanie. I think it would just enhance the collection of Millennium figures. Melanie
