well I just found out about G3 so can't say any thing about them.

but G1 boy,girl & are the same mesh.

G2 boy,girl are the same mesh,maybe it's just a morph or might have been mapped different or rig different etc etc I don't know why there's a boy,girl difference.

you can still see a lot of V3,4 not SubDed yet in Genesis. 

when I upgrade daz studio I'll get G3 ,I guess there the same boy,girl mesh also.

if they got G2 to work in DSON there's no reason why G3 won't eather .there's always kinks in new tech ,just iron out the wrinkles ;)
