Sure there is.. double the amount of ram needed for the application. In addition, all the advanced rigging systems mentioned are ALL for very expensive high end applications, which would mean a significant investment in both research and developement, with potentially a low income gain as a result.

Something we've been discussion in other forums, is that poser as it even is now, has become very complex to use, and it's target market is supposedly beginners interested in cheap and esy 3d work.

Yeah is sucks if you are an advanced user, like many of us are, BUT many of the advanced people have also invested in better renderng and rigging applications at our levels.

IMHO, poser's best target market is the beginning user.. once they become advanced, most move on to something more advanced, but also more expensive as well.

I think the biggest issues in the poser market now, are that users now are expected to know a LOT more about how to use content then in the old days.

Example:

Load a figure with lot of add on morphs.

Old days: Install and Load a larger footprint cr2, and spin dials. Easy for a beginner,

V4: install the base figure. Initialize it. Install a morph set. Initilize v4 again, install another morph set. initilaize AGAIN. Now dial spin.

How many times have we seen people not being able to get v4 with morphs to work here? Or M4?

I think the current rigging system is fine for the intended userbase, and I'm not sure if they did an expensive  "super poser 9" with an enhanced rigging system like higher end applications would be successful in the marketplace. Higher end users shun poser as a beginner's toy.

Way too many people take way too many things way too seriously.
