A rather simple to implement way to go forward would be:

• Full implementation of Cycles and the Principled BSDF as default material room setup. (Replacing the FireFly and SuperFly root node)
• Full implementation of Eevee to replace the current preview mode.

However ; and please stay constructive here.

We can not allow a company to become a slave of another company's technology.

• We don't want Poser/Renderosity/Bondware to depend on DAZ for figure technology.

• We also don't want Poser/Renderosity/Bondware to depend on Blender.org for rendering technology.

If you make yourself "depend" on an external company's technology? "They" will always have it first, and you are always running behind playing catch-up.

And the reaction will be the same as always : Why pay for something we can get for free.

On the issue of future figures. => If you want figures to behave like humans, you need a human muscle geometry to make movements and muscle mass changes "believable". => Orion and Venus seem to go in the right direction.
