Teyon, I was thinking the exact same thing.  It would be nice to see a "Poser Professional" application.  Something specifically for professional level animation.

Other features to consider:

-Interlaced rendering (mind you with HD this might be moot in a few years)
-True Bezier curve animation pallete
-A more robust timeline and key frame management system with the ability to "mark an in point and out point" (like the Avid or Final Cut systems)
-more robust support for third party plug-ins.  (It would be nice to see plug-ins for fluids, for example)

As it is Poser has an amazing (surprising) amount of animation features once you delve deep into it, but a pro level package would be very welcomed.

I work in television as an editor and graphics animator.  Usually I use 3D Studio Max, but I have used Poser on a few occasions with great success.  Forget reputation in the 3D community, Producers only care about results, and I've impressed a few producers with Poser.

I'd really like to see it taken to the next level.
