Many (all?) Genesis figures come with 4th Gen (And even 3rd Gen) "legacy" shapes.

While these legacy shapes still feature the original Genesis rigging, it's quite easy to convert them to the original 3rd or 4th Generation Poser rigging.

Here is Genesis 2 Male converted into a native Poser figure, complete with Michael 4's shape and rigging:

This figure can use all M4 poses and clothing. Has a more realistic face, takes G2M textures and head morphs, and weighs 2/3rd less than M4 does.

Poser has such powerful tools, it's a shame they are hardly ever utilized to their full potential.

BTW, DAZ seems to be fine with the fact that pretty much all Genesis figures have one-click access to each others clothing, including the vast V4 and M4 wardrobe.

So, even though they see selling new clothing as their main buisiness model, they don't mind "hand-me-downs" cutting into their profit margin.

That makes me wonder if they'd be willing to "license" the V4 and M4 shapes and rigging to a third party.

All things considered, a "native" Poser figure, but with "out of the box" V4 and M4 clothing compatibility might make a good "interim" solution for the currently content starved Poser community.

(Not to mention that I find many V4/M4 clothing better made than their more modern counterparts, anyway)
