SP3 is probably my favorite female figure. Perhaps part of the problem was that she was seen as an also-ran to V3, but she also had some flaws that probably hurt her standing among the cheesecake crowd.

The original Steph was made of the Michael mesh, and perhaps SP3's origin was with M3.  For whatever reason, she had a bit of a horse face.  Nothing you couldn't fix with a few morphs, but how a figure looks "out of the box" matters.  She also had small boobs that got a tad faceted if you blew them too much. 

As for your original question...we may be about to find out.  :-)
