I am not sure what exactly is meant by "ghost bones". But i think the Genesis figure has one interesting addition: The "pelvis" bone, which is exactly like the "hip" bone but oriented the other way around and inserted between the hip and the legs. That allows me to rotate the hip while the upper body stays in place. Very useful if i posed the entire figure, but decided to make an adjustment to the hip afterwards. With the older figures that would mean to rotate the hip, counter-rotate the abdomen, counter-rotate the chest and so on all the way down to the fingertips, which is very time consuming. It is also not that difficult to make; just insert the additional bone and change the hierarchy in the cr2. What Genesis does not have, however, is an application of the same principle to the rest of the skeleton. I.e. i would like to have a reversed abdomen, chest, and neck. I tried this once with Poser2010 and got it to work, but it was a very unpleasant excercise: Everything has to be done in a text editor; Poser tends to destroy all the setup whenever the Setup-screen is touched; and the cr2 format is rather difficult to understand and of course not documented anywhere. So in principle exactly the thing a figure vendor should do (so that i can just smack together a pose and hit the render button). Perhaps it would be easier with the addition of the new "animated joint centers" feature (which i do not have).
