Was observing the discussion here over recent days, and my personal unbiased opinion on the V4 thing is this:

The difference in realism between V4 and V7 is blatantly obvious.  I've not even visited the page for V7, yet the improvements over even V6 are noticable enough just by looking at the stuff people are posting.  Even that 'quickie' Male_M3dia posted demonstrates what a good figure she is.  For a quickie to look as good as that, it's surely testament to the quality of the figure.  They seem to have worked very hard on improving the 'shift' of things, like when arms are raised and knees are bent etc, and the lack of it was something I didn't like about the previous versions - cause I felt it still fell short of what the technology allowed.  This new V7 figure, though, have to say I think it's very nice indeed.  I only hope Roxie doesn't see this comment or I'm in BIG trouble.  But yup, V7 is a definite improvement, in fact I'm half tempted to download her and have a go at making her look like the girl in the attached video, cause for some reason she kinda looks like a Vickie in a lot of ways, although I can't put my finger why that is.

BTW, it's a Super-Catchy and massively underrated track this is (in fact it's easily one of my favourites).
This should have been a massive hit, but strangely it's relatively unknown despite the singer's fame :
