Just my 2 cents, although I was not into 3d yet when V3/V4 switch did happen, I can clearly see why all vendors support went into V4, V4 was looking much better, realistic, and anything you want (never used V3, but when I see a V3 picture, usually I can see it's a V3).

I don't feel the same improvement between V4 and Genesis, I mean Genesis doesn't make V4 look like an old-fashioned figure at all. Without talking about the troubles to get Genesis working (Poser people needed to learn Daz 4 some time ago, now they need to work with that DSON thing, doesn't seem to be 100% reliable).

I'm very glad vendors here are still supporting V4, because I think Daz has 'officially ' dropped V4 support 1 or 2 month ago (nothing for V4 among new releases, Daz vendors selling stuff on other shops more and more, Daz front shop looking as if V4  never existed, etc).

Kudos to Renderosity, V4 vendors, and Rdna too, for that :)
