I too keep hoping someone comes up with a realistic breastform that is less firm and has more of a natural breast feel, jiggle, and sway to it.
Would be great if they could even hang differently like a real breast depending on whether you are standing, leaning over, or laying down.
They've made great strides making breast forms look natural (and have a somewhat better feel), but I want something that really makes me feel like I have real boobs, not just something that looks good in a bra.
Maybe I'll just have to design something on my own .
