I really don't understand all the impatience.  DS4 has only been out a short time, and P9/PP2012 have only been out a short time-- since September or so.  Three months is a very short time in terms of software development.  The technology behind DS4/Genesis has been in development for at least two or three years, if not longer, and I'm sure the new features in P9/PP2012 have been in devolopment for about as long. 

I also don't understand the tendency to jump to conclusions about what is or is not a priority with either DAZ or Smith Micro.  I don't know what's going on inside DAZ, or which projects have high priority and which ones don't, and neither does anybody else who doesn't actually work at DAZ.  Same for Smith Micro.  The fact that DAZ has been quiet about the exporter doesn't mean that DAZ isn't working on it-- and likewise, the fact that SM has been quiet doesn't mean that it isn't working on a solution to the incompatibility problem.

A company has to keep many things fairly "close to the vest" while they're being developed.  Suppose SM announced today that, yes, it's going to incorporate DS4 technology into Poser-- but then, a few weeks from now, it ran into problems that make that impossible.  SM would end up looking very stupid.  Or suppose DAZ announced that the exporter was "almost done" and would be ready in another week-- but then ran into problems that caused the thing to be delayed for months.  DAZ would end up looking like a liar, or an idiot, or both.

Unless you work for a company-- and maybe not even then, depending on what your position is-- you're simply not in a position even to speculate about what is going on inside that company or what it's working on or anything else.
