I love you Coleman, but you haven't really thought this through. 

To address your items:

1.  VUE is a lanscape program - Poser isn't. Adding instancing would probably require leaving every single bit of legacy content behind - good luck in selling that to the Poser user base.  I would suggest that you open a cr2 or a pp2 file in a text editor and read it sometime. 

2a.  The SM figures aren't designed to be supermodels - they are designed to be NORMAL people - wearing normal clothing.  The biggest difference between V4 & Sydney - V4 has a cottage industry of mesh fixes - Sydney doesn't. 

I prefer the SM figures - but then I am not a third rate Elvgren wannabe.  I have progressed from NVIATWAS.

2b.  Any new figure is going to be met by people deliberately sowing FUD.  Some will be doing it because their business depends on supporting a different figure. * Others will be focusing on making mountains out of molehills on any percieved flaw (In all seriousness, how many people here are making renders of a figure's armpits?).  Still others will be yammering on about how none of us actually need new figures, because any of us can adjust Posette in (modeling program of your choice).  These folks have yet to figure out that most Poser users not only do not have those skill sets, but have absolutely no interest in aquiring them.

2c.  Any new figure success is completely dependant on vendor buy-in.  I'll ask again:

HOW DO YOU PROPOSE TO FORCE THE VENDORS TO SUPPORT A NEW FIGURE?  "I'm an artist, I only make what I am interested in" is the Vendor's battle-cry both here and in other storefronts.  Right along with "I once made a piece of content for <M3, Apollo Maximus, Jessi 1 etc>.  I made a very niche product - it didn't sell (the fact that it was both more expensive and less capable than my other products is irrelevant), therefore I will never make anything for any figure not named V4."

HOW DO YOU PROPOSE TO FORCE THE VENDORS TO SUPPORT NEW FEATURES?  Most vendors are aggressively unwilling to move past the Poser 6 feature set.  The fact that almost the entire user base is using Poser 7 or later is irrelevant to them.  Which btw, is also an issue for your 1st item.  

3.  Why should anyone pay attention to the galleries here?  I have been here almost 10 years now, and today was the first day that I actually spent time in the galleries.  Sturgeon's Law (ninety percent of everything is crap ) applies.

4a.  As far as "Native DSON in Poser" - your suggestion means that DAZ would make the money off content and SM would be stuck with all of the support costs.  This is precisely why SM refused to add DSON to the Poser code-base.  As it currently stands, it only takes about 15 minutes to convert genesis to a Poser native figure - No DSON necessary.

4b.  What does genesis actually add (other than access to Dariofish's HFS aliens?)  All of the characters made for genesis over the past few years look just like their Gen4 predecessors - as does the clothing (idler168 shoes for genesis look great - I have the exact same shoes he made for Miki 1 and P6 Jessi about 8 years ago).
