I'm not sure if it's Miki3 with a future released character or not.  Could be a morphed and textured Alyson.  I remember Poser 6 had the awesome character for Miki1 on the box and it really didn't look like her straight loaded up.

Well, it's the 31th and no Miki3.  Hopefully they'll release her in June, or at least tell us what's going on.
