Well, Daz could immediately stop further V4 growth by pulling it from the market, however unlikely that would be.

Personally, I use the poser pro's (2010 or 2012), Hex, Carrara, and/or ZBrush for everything. DS 4 is installed, but I'm waiting for them to get it working with my tablet mouse, so it's not used.
I make a good living from my website so I have no real interest in being a content provider, and am not concerned with being recognized for my "art". I post very few renders, except to a nondescript, nonsocializing account on DA. Believe me, you can learn a lot about what works or not within 5 minutes after posting there in relative anonymity.

On the subd thing, poser seems to do quite well with it's smoothing on characters with the smoothing set for 70 degrees. One of my favorite characters is V4.2 that calls the 17k poly V4 LOD mesh with all my favorite morphs imported with MorCloth. So, I don't think Genesis being low poly would be that much of a problem in poser.

Here's a render of 17k V4 made for a post I thought about making on one of the lowpoly  threads, but decided against.
Heck, it's probably junk anyway. :-)
