I'm not familiar with the high end apps, but it seems to me that someone needs to think outside the box to take the next step. Rigging based on bones is conceptually limited. Obviously, you can't normally bend in the middle of a bone (unless something has gone wrong :) ), but the actual actors in movement are muscles.

I guess movement controls based on muscles might over-complicate things, though. It would require a learning curve even to use, much less build.
