the ideal poser skeleton would have weight mapped joints and/or flexible bones, etc.... industry standard features which just do not exist in poser's current prehistoric acsii-based CR2 rigging system, and sadly probably wont exist in the next one -- especially with people asking for the wrong features.

so i predict that in poser 10 we will have global illumination, a complete subdivision surfaces and NURBS modeling suite, a particle generator and physics system, network rendering, 2 million polygon base models (because everyone knows that higher resolution is better, right?) with 200 body part groups and 400 JCMs, but still wont be able to lift a character's arms over their heads in a render without spending hours on postwork.
