Vickie may cost about the same as the Poser 4 upgrade. But the true point is that you had to pay for the Poser upgrade. When Zygote upgraded Vickie, they offered it for free. While it is true that many features of the upgrade were things that we wanted Zygote never implied that they would be in their original model so the upgrade was effectively a new product. Additonally, they offered a promotional time limited discount on the initial product. I did not receive such an offer with my initial Poser purchase.
