You forgot the most important question will it work in poser7.  A lot of issues of poser7 were related to V4. Because V4 was published some weeks before poser7 was, many people were blaming poser7 for this, but I believe that the main cause was that V4 was optimised for DAZ-studio. Some of the new features of Poser7 like external morph targets and the new morphing took, just didn't work with V4 and made poser7 crash.
I hope Daz has learned from that experience and started talking with the Poser-people (Smith-micros at the moment)
If they use the same policy with selling of A4 as V4, there will be a free or an allmost free basic version and an additional "pro" version, with morphs, skins, clothes and more bells and whistles for a more expensive price. It's just those additional thingies that cause the troubles so it's good to know DAZ has 30day, payback policy.
Not that I don't like Aiko, I just don't use her as often as V4, but if A4 causes the same problems as V4 did, no one is going to be happy.

Best regards,
