I think it's more likely that every user eventually finds something that could be improved in Poser.  The more versions you've used, the more things you've probably found that need improved.  The things is, some of those things have needed improved for a very long time, and aren't peripheral things (like the faceroom was to me-I still haven't tried it) but are the core functions of the program.  I think we can all agree that Poser needed multiple undos (wondering if the camera undo will be seperate from the figure undo...) and has always had problems concerning rigging, or more precisely deforming of joints.  There's a tendency for many users to only notice when their own complaints are being addressed or ignored.  I can understand being underwhelmed by the lip-syncing if I already had bought and learned a 3rd party solution.  Who can't say though that Poser should have lip-syncing given it's aim and other features?  Of course that should be in there.  Likewise, we will eventually need better rigging or some kind of ERC/morph/magnet overhaul of the current deform system.  Things like soft select, or GLSL previews would have been crazy talk a few years ago, but are necessary and doable as witnessed in Quidam, Cinema4D etc.  I still don't consider content a "feature", but I'll concede that it may be a reason to upgrade for some.  Let's just hope there are more foundation improvements and refinements we can all benefit from, and a little something for everyone else to keep them happy.
