"Morph Follower - This feature allows you to add support for new figures in old clothing by automatically creating new morphs to fit an unsupported shape. (Based on technology by EvilInnocence)" - so they've apparently incorporated Crossdresser  which would be the equivalent of P8 including WW.

"Map Transfer - This allows you to convert a texture from one figure's UV's so they can be used on another figure's UV's." - I didn't know they had built in texture conversion as well.

On the renderers, Daz "seems" to be using the stock 3Delight engine and picking and choosing what functionality to expose inside DS. I thought that Poser  was using Pixels3D's Tempest engine as Firefly but recent posts state that Stewer wrote the P8 renderer so I'm confused. Maybe they bought the source and he's modifying it but it sounds more like a new engine.
